It's perfectly possible to get (pretty low quality) broadcast video into 160kB/s (Bytes not bits).
Tivo varies from 192kB/s for its lowest quality (giving 12 and a half days on this machine) to 672kB/s for the highest (giving about 3 and a half days).
28 days will only allow VCD quality but people put up with VHS for 20 years, and that was worse than VCD.
The problem with benchmarks is that you have one group that only likes to look at synthetic benchmarks (you appear to be in that group). The other group would rather look at "real world" benchmarks. In this case, comparing Word on a PC and a Mac.
The PC World benchmark says the Athlon is faster in the real world. Well looking at SPEC published benchmarks for the Athlon FX-51:
2GHz G5 (from Apple, not on SPEC): 840 (float), 800 (int)
This universal machine uses Combinators, specifically S-K combinators.
S-K combinators (and other combinations) like Turing Machines and Lambda calculus can express everything we can possibly compute (all possible computations).
Expressions are built up by applying combinators (eg A and B are expressions AB is an expression with A applied to argument B).
Primitive combinators define reduction rules. In S-K combinators we have the primitives S and K.
K is defined as: (K x) y -> x for any expression x and y.
S is defined as ((S f) g) x -> (f x)(g x) for any expression f, g and x. (x, y, f and g are just part of the notation not variables)
By applying S and K you can build up expressions expressing all possible computations (though not very compactly).
You can now repeatedly apply the two rules to an expression to obtain a normal form (or repeatedly apply to the left most reducible element to obtain a head normal form).
For example:
S[1]K[1]K[2]S[2] -> K[1]S[2](K[2]S[2]) -> S[2]
(the square brackets indicate subscripts for the purpose of telling the combinators apart - they imply nothing)
And S[2] is a normal form.
Many other combinators are normally introduced to increase expressiveness but above you have the basic principles.
AOL buy RedHat, become the dominant Linux retailer and within a few years Microsoft are effectively dead just surviving on revenue from joysticks and keyboards.
But then what happens? AOL don't want to spend money improving the OS and the Open Source community has far less people wanting to work to support AOL. Linux is now just a platform to support the AOLTW services platform and everyone is paying them $200/month for those services.
So software is effectively dead in the water. With no companies making large sums of money from it no one wants to put money into R&D. Why buy Windows when you get AOL/Linux free on CD? Why support Opera when you get AOL/Mozilla free on the same CD?
So software becomes a platform to generate revenue for services and hardware companies. This is why Sun is so keen on (some aspects of) open source.
AOL is hated for some very good reasons. At least Microsoft funds Microsoft Research and puts money into software R&D. AOLTW is a marketing company and Linux will become just be one more way of leveraging their monopoly in Internet services.
Sega have tried this before in association with Amstrad. You could buy a PC (486/Early Pentium?) with a Mega Drive built in (it was on the motherboard not a card I think). It didn't last very long but the Mega Drive was near the end of it's life cycle anyway.

Athlon 64 3200+ (from AMD, on SPEC): 1266 (float), 1180 (int)
That's about 50% faster for the Athlon, the G5 may have been the fastest personal computer when it was launched but it isn't any more.
Surprise, surprise, we do spend loads of money on countries that need schools and agricultural help and so on
In actual fact the U.S. foreign aid budget is a mere 0.117 percent of its GNP, the lowest percentage in the world.
The sad history of development aid ...
Perhaps if the U.S. didn't go round killing democratically elected leaders those countries wouldn't be in the state they are today.
There's plenty of science fiction about small computer devices, some of which could store personal data. There's a useful summary here.
