Yeah, and a search for "Real Player ate my dog" comes up 119,000 hits. Does that mean that there are 119,000 instances of people discussing Real Player eating their dogs?

The Pentium IV-M is not a desktop Pentium IV chip (and I was referring to higher speed desktop PIV's anyway, like 2.8GHz and up, which are insane power hogs)
Athlon64 laptops with ATI Radeon 9600m video chips have been available since November of 2003. Why would anyone want a desktop Pentium IV chip in their laptop? You do realize that they can go for all of an hour before needing to be recharged? How about that the systems aren't really "laptops" at all, unless you like your pants melting to your medium-rare flesh. The Athlon64 is a better gaming chip and allows for decent battery life (3+ hours) because of "Cool'n'quiet". In the Intel camp, the Pentium-M is an extremely capable processor and uses even less power than the Athlon64. IBM and VoodooPC both have Pentium-M laptops with game-worthy video capabilities.

I prefer to get Opterons over "Xeopterons", if for no other reason than because Intel blatantly ripped off the 64-bit extensions from AMD, and didn't even bother mentioning them in the "ia32e" specification documentation.
Granted, AMD is making designs based on Intel's ancient and decrepit architecture, but at least they acknowledge this and give Intel credit where credit is due. Many of AMD's AMD64 technology papers are published as the differences between Intel's IA32 papers and their design.
Of course, the fact that Opterons scale better due to not sharing all memory bandwidth between CPUs, using HyperTransport for interCPU communication, and having a dedicated and integrated low-latency memory controller for each individual CPU helps in the Opteron-vs-Xeopteron choice as well....
You have a good point, as using Windows Update is easier (or at least as easy) as any GNU/Linux update method, and can be made automatic very easily (like some GNU/Linux update methods). One noteworthy difference, however, is that none of the BSD or GNU/Linux update methods tell the vendor the software (and their versions) that you run. To their credit, at least, none of them (including Microsoft) collect any actual personally identifiable information.
C# is not run as interpreted bytecode (which would be slow); it is "compiled" to bytecode and then, when the program is first run, compiled to native code. It is about 10-20% slower than a similar program written in C++, but for most GUI apps on modern machines, this does not matter. Of course, for "real programmers", C and C++ still grant you much more power. Function pointers, inline assembly, easy bitwise operations... C# is fine for many programs, but just TRY to implement a network protocol using it! MD5 is another good one. I haven't tried it myself, but have a friend that was forced to by a company thoroughly brainwashed by Microsoft.
Hard drives are not manufactured and binned like processors. They are built with platters of a static size. This is absurd to the point that it is a waste of time to argue about. Ask about this moron's letter on Storagereview.com. StorageReview has several users who are hard drive engineers, including the head of the SCSI division of a major manufacturer. I've been following the site for years. You tend to pick up a few things. Trust me--if you are interested in seeing if this is really true, do some research. If not, well, you've just chosen to take one Joe Internet User's word over another's word.
Defining a gigabyte as 1,073,741,824 bytes is no more or less "real" than defining it as 1,000,000,000 bytes. Nothing about the way hard drives work makes it more logical to measure using the binary common use of the prefix over the traditional SI one.
If anything, Windows and whatever other reporting software used is incorrect, because "Giga" is an SI standard prefix used in science and mathematics meaning "One billion", just like "mega" is "one million" and micro is "one millionth."
In the old days, "kilobyte" was used when referring to 2^10 (1024) bytes because it was conveniently close to 1000, which is the meaning of the "kilo" prefix. The base-2 to base-10 similarity becomes ever wider as the values multiply. Go ahead and look at the next two sequences in which binary and decimal powers are "close".
That said, ultimately common use is what defines the meaning of words, but the common use of a word by no means invalidates the original terminology from which it was derived!
If this is real which is doubtfull it is probably a marketing trick. The drive manufactures proably make one drive and sell it as 3 different drives in different capacities.
Actually, this is exactly what they do. The difference, however, is that the lower-end (smaller) drives are identical except that they come with fewer platters. For example, a 160GB hard drive today likely has two 80GB platters, whereas an 80GB drive probably has one (though different combinations of different sizes are of course used, depending on when the hard drive was manufactured and other factors)
In some cases, a hard drive will be sold with a greater potential capacity than its available capacity. For example, a drive with two 60GB platters may be sold as a 100GB drive, the platters having been "short stroked". This has nothing to do with the absurd technique described in the Inquirer article, and I doubt that it is possible to recover the lost space. Hard drives are the highest precision mechanical devices that most people have in their home--moreso than processors, high-end printer heads, or toasters. They are not something that you want to physically modify.
See the following highly informative and interesting (if you are a geek) posts by a Maxtor engineer: Here here and here
DirecTV and Dish Network both have a comparable number of channels--Dish has more non-English channels and DirecTV has more sports channels. With this in mind, does it matter if Dish has more capacity if they do not actually use it?
Interestingly, Dish and DirecTV share several satellites at the 110 and 119 positions. Oddly, the programming is duplicated (that is, they do not share the same streams--there are two CNNs, two SciFi channels). Perhaps it is impractical to modify streams to turn DirecTV commercials into Dish Network commercials and vice-versa.
DirecTV charges by the access card, not by the tuner, so no, the second tuner costs nothing.
Exception: (This isn't public information yet) DirecTV will soon begin testing dual-output conventional receivers which connect to two TVs. A repeater for the second TV's remote will connect to the cable and somehow its signal is routed through that cable, along with the television programming. Sorry, you cannot request these units as a very limited number are being made. They are only in the testing phase and may not be put into mass production--it depends on customer response. Anyway, these receivers have one access card, but are charged as two receivers (because they connect to two TVs simultaneously). Thus, I guess it would be more accurate to say that DirecTV charged by the number of televisions that can simultaneously display different channels.
Perhaps a key use is not to use neurons to improve silicon chips, but to do the opposite.
Who knows, in a few decades we might have people deleting their childhood to store and smuggle hundreds of GB of information about the cure for a major epidemic that an evil pharmaceutical company is exploiting for profit.
1) Memory hotplugging exists today. It's hardly an insurmountable problem.
2) Even if it were (and didn't already exist) MRAM (Magnetic RAM) is non-volatile.
Still, I have to admit that hard drives have been "scheduled" to be replaced or obsoleted 3 or 4 times now, and every time, they have survived. They are just cheap and versatile and "fast enough", and for applications that want a high sustained transfer rate (STR), they are really quite fast. Fujitsu's latest SCSI drive can handle nearly 80MB/sec sustained for more than half of its capacity. Yo would need a hell of an expensive FLASH controller to outpace that, and FLASH technology is still hampered by a "limited number" of write operations before it dies.
The cost is... Absurd. Even for a top-end gaming laptop.
Let's see. For $2,500, I can get an Athlon64 laptop which: 1) Dominates gaming performance (games, you know, the point of the Dell laptop's existance) 2) Will run for more than 45 minutes on battery, becaues of Cool'n'Quiet technology. Mine runs for about 3 hours on battery. Honestly, a high end Pentium IV in a laptop? While we live in infinite battery land, why not add a 21" CRT monitor? 3) Isn't a Dell laptop.
Or, if I still like Dell (they aren't bad for the price sometimes), and am not one of the 95% of the world's clueless that still believes the CPU clockspeed = performance, I can buy a Dell Inspiron 8600 with a 1.7GHz Pentium M (which is very close or equal in performance to a 3GHz Pentium IV in most tasks), with an ATI Radeon 9600 Mobile and 1GB of memory, for about $2,600.
I have to say, this new Dell laptop is clearly targetted towards complete idiots with too much money on their hands. It isn't even a "just for rich folks which can afford the finest things in life" unit, because those "rich folks" can get a hell of a lot more laptop for the price, and not have the cheap stigma that is attached to every Dell laptop (except the admittedly very good Dell Precision series (which is made by the same ODM that builds some of IBM's laptops).

Couldn't tell you what "aureal density" means.
That's probably because I can't type. You may want to read this reference for " areal " density, though.
Be sure to use similarly advanced techniques to "defraggle" your hard drive.
Sorry, but this is complete bullshit.
Did aureal density technology increase to 200GB/platter overnight? No.
