I think what we may see as a trend in the next few years is the switch from 3.5" 1/3 height hard drives to 2.5" 1/4 height hard drives with Serial ATA connectors as desktop computer hard drives in the next few years.
There are a number of advantages going to 2.5" drives: 1) they run quite a bit cooler than 3.5" hard drives; 2) the power consumption is much lower than 3.5" hard drives; and 3) it will allow even smaller-sized BTX form factor system cases.
1. Because of human curiosity. From the very beginning of human existance, we've always asked what is out there in the whole wide world. It's this curiosity that has driven humanity to explore the Earth's surface, the oceans and into space. What you're suggesting effectively kills human advancement.
2. The enormous scientific spinoffs from the science and engineering developing a spacecraft flying to Mars and back. Indeed, the computer you're using is one of the major spinoffs from the US space program, and medical sciences have advanced tremendously because of the need to study the unknowns of humans travelling for long periods of time in space. The scientific spinoffs from the engineering and science needed to develop a manned Mars mission could be just as big as what we got from the US space program of the 1960's.
It'll be a long time until any of the (former) X Prize teams get anything into orbit, and when they do it won't be very similar to the purpose-built vehicles they've been working on up until now.
You're forgetting that Scaled Composites (Burt Rutan's company) was heavily involved with both the McDonnell-Douglas Delta Clipper and Lockheed Martin Venture Star programs. Though these programs were not complete successes, it does mean Scaled Composites has actual experience in building real spacecraft and that means Rutan has a pretty good idea of the engineering needed to build a spacecraft to reach low Earth orbit (LEO) at reasonable cost.
Interesting you would talk about speeding up the rest of the computer because with AMD putting the northbridge memory controller on the CPU itself, the Hypertransport motherboard level data connections, DDR2 system RAM, PCI Express, Serial ATA, and UltraSCSI 320, most of the other components on the computer are also getting quite a bit faster, too. And external connections are getting faster with USB 2.0 and IEEE-1394b becoming increasingly common, too.
I think the main reason why the Sempron 3100+ runs quite a bit faster than your Athlon 1.4 GHz CPU is that the CPU architecture is extensively based on the highly-efficient Opteron/Athlon 64 design, which means very efficient system memory access and very efficient access to the on-CPU die L1/L2 memory cache. That evens even though the Sempron 3100+ runs only 400 MHz faster CPU clock speed compared to the Athlon 1.4 GHz, other CPU architectural improvements improve overall performance quite a bit.
By the way, you might want to know that future Pentum 4 variants will base their core on the Pentium M CPU architecture; you'll see these new Pentium 4 variants arrive on the market in 2005.
I often find myself wondering what would happen if the Hindenberg never made the world terrified of airships as methods of mass transportation.
The result would be that the cruise ship industry would be smaller than it is now. You'll be seeing a lot of helium-filled rigid airships operating on cruise flights at places like the Caribbean and the Mediterranean Seas. Also, airships would have switched to modern materials, making them capable of carrying cargo in places where ground transportation infrastructure are poor or non-existant.
Given the fact that Trey Parker and Matt Stone have done quite a number on the Hollywood Left in the past, I'm not surprised at Sean Penn's reaction to the movie.

That would be great if it weren't for those insane elitist NIMBY's that are holding up innovative wind power programs such as the proposed wind farm off the coast of Massachuetts.
I'll put the wind farm southeast of Nantucket Island (that will avoid the impact on air and sea traffic between Martha's Vineyard and Nantucket Island and the US mainland) with 200 three-megawatt wind turbines; that will generate some 600 MW of power, more than enough to power every building on both Nantucket Island and Martha's Vineyard.
The primary reason that you don't see this type of pollution in the US is that the federal and local governments have taken a very agressive stance on NOx and SOx reduction from transportation (cars, trucks, and trains) and power plant (coal) sources. Some here have complained that the attack on these pollutants (along with particulate emission) has a lot to do with our lower fuel economy standards, as the rules make it pretty difficult, for instance, to introduce diesel powered cars, and they mandate the use of catalytic converters.
The primary reason why oxides of nitrogen and sulfur dioxide emissions are heavily regulated is that these pollutants have far more serious effects on lower altitude air quality than other pollutants. That's why you used to have extremely serious smog problems in the Los Angeles area where the oxides of nitrogen and sulfur dioxide would literally turn the sky brown for weeks on end, and why many older European buildings suffered serious damage from the effects of these gases.
Anyway, the phaseout of high-sulfur diesel fuel (which will be complete by September 2006) will allow diesel engines to be sold in all 50 US states again, because this will allow for the wide availability of next-generation diesel engines with extremely precise fuel delivery (thanks to common-rail fuel delivery and direct fuel injection into combustion chamber) and improved exhaust emission controls (namely a new catalytic converter that not only drastically reduces normal exhaust pollutants of oxides of nitrogen, sulfur dioxide and unburned hydrocarbons, but also "burns off" diesel particulates). Switching to these new cleaner diesel engines also has another advantage: you dramatically reduce carbon dioxide output because diesel engines are 35-45% more fuel efficient than gasoline engines of the same power output. Finally, diesel engines are easily adaptable to non-petroleum based biodiesel fuel (after all, Rudolf Diesel's first prototype engine ran off peanut oil!); this means we could find a source of biomass (e.g., certain types of algae) that when produced on a very large scale could power these diesel engines pretty much forever!:-)
All Microsoft needs to do to squash Firefox is to buy out the people who developed the Maxthon plugin for IE and offer it for IE 5.5 and later users through Windows Update. That right there will pretty much dry up much of the market for Firefox.

Actually, the main reason why the Pentium M CPU was considered a success was the fact Intel stuffed a massive amount of cache memory onto the CPU die (I believe the Pentium M CPU die has 1024 KB or higher of CPU memory cache). Small wonder why future Pentium CPU's for desktop computers will be derived from the Pentium M design.
Ever since the original Pentium, Intels own x86 cpu's have essentially been RISC processors inside, just like the Athlon.
That is true, but Intel's X86 core is still heavily derived from the CPU core pioneered on the Pentium Pro CPU of the middle 1990's. Indeed, the Pentium II/III CPU's were essentially improvements from the PPro CPU core.
Meanwhile, AMD's Athlon CPU core was pretty much developed from the ground up (thanks to their acquisition of NexGen), and because it is close to a clean sheet design even the earliest Athlons were already out-performing the equivalent Pentium III CPU's on the equivalent CPU clock basis. Because the Athlon CPU core sported such high processing efficiency, when the Athlon XP CPU's came out AMD CPU's could still compete against the Intel Pentium 4 CPU's; for example, the Athlon XP 2400+ CPU matched up surprisingly well against the Pentium 4 2.4 GHz CPU even though the clock speed of the AMD CPU was was lower.
Actually, if you're willing to invest in a few hundred dollars you can bring your computer box up to date.
For example, if your computer case supports the ATX form factor you could get an Abit VA-10 motherboard, an AMD Sempron 2400+ boxed CPU (e.g., CPU with CPU fan already installed), and 512 MB of DDR333 DDR-SDRAM for the few hundred dollars I mentioned. The result would be dramatic increases in performance--just the CPU performance will probably be 8-10 times what you have now.:-)

Actually, the x86 CPU architecture is still alive thanks to a company called AMD.:-)
AMD's groundbreaking Athlon CPU core is far superior to what Intel has, and the Athlon XP showed that you don't need ridiculous clock speeds to get superior overall CPU performance, thanks to the the combination of the very efficient Athlon CPU core and generous on-die L1/L2 CPU memory caches. AMD's decision to put the memory controller onto the CPU die with the Opteron/Athlon 64 CPU's also demonstrates how to get superior CPU performance without running high CPU clock speeds like Intel needs to do with the Pentium 4 CPU's.
The biggest fiasco for Intel was the Itanium project, which showed while it was a technically-excellent CPU it also exposed the big problem of lack of software to support the CPU.
Meanwhile, AMD brought new life to the X86 architecture with a modern developed from scratch CPU design using the Athlon CPU core. Note that AMD's CPU's have truly impressive performance per CPU clock cycle, and AMD's decision to move the memory controller onto the CPU die with the Opteron/Athlon 64 CPU's allows AMD to match the performance of the latest Intel Pentium 4 CPU's without Intel's need to run very high CPU clock speeds.
What's interesting is that Scaled Composites were heavily involved in both the McDonnell-Douglas Delta Clipper and Lockheed Martin VentureStar projects. While they were not complete successes, the experience learned from working on these projects will already give Burt Rutan's team a major headstart to build something to win the US$50 million America's Space Prize for the first low-cost manned orbital spacecraft.
If Scaled Composites succeeds on this project, it will revolutionize access to space on an unprecedented scale.
Actually, rural Canada can really benefit from WiMAX because given the low population density of northern Canada, it's probably the only way to get broadband cheaply to customers out in the boonies.
Like I said originally, because a large fraction of the telecommunications infrastructure is unsuited for broadband here in the USA especially on the last mile connection, this will finally get broadband Internet to the the vast majority of Americans.
There are a couple of issues that have to be considered now that Howard Stern will become a Sirius satellite-only show:
1. Will fans pony up the big bucks for a Sirius satellite radio receiver and pay the monthly fee just to hear Stern? Remember, unlike XM satellite radio, Sirius is still quite rare as pre-installed on new cars.
2. Will Stern be unfettered by censorship and take the show to extremely raunchy levels of sexual descriptions and use of raunchy language?
Despite Sirius getting NFL broadcasts, they're still way behind XM in terms of public recognition.

Why do I think the first company that will roll out WiMAX nationally will be Verizon Wireless?
I think there is a huge advantage for WiMAX compared to WiFi: the coverage area for a WiMAX is pretty much close to line of sight, while WiFi has a very, very tiny coverage area in comparison. Also, WiMAX can cover thousands of users per antenna, far more than WiFi setups.

The reason why 802.16 WiMax and its related 802.20 mobile wireless networking has generated much interest in the USA is the very fact that it's a lot cheaper to put up tranceiver towers for WiMax than to upgrade older residence and/or business locations to accept cable or DSL broadband. Also, the USA has enough rural areas where WiMax is probably the only way rural residents can get broadband.
WiMax is actually quite fast: it is theoretically capable of up data transfer rates far above that of wired residential broadband (I think the max limit is about 45 mbps download speeds).
In short, we have too much legacy telecommunications wiring that are not well-suited for broadband, and WiMax will bypass this limitation.
