I'll help. the problem with 360's is that components over heat, the gpu is often involved. smaller chips are useful for two reasons. they are smaller so they get the same amount of power in a smaller space meaning better efficiency (less energy used), with energy equating to heat. the other reason is the size itself. on chips the electricity moves from place to place. since they arent superconductors some electricityis lost. the lost electricity is energy which turns into heat. on smaller chips they travel less so less is lost (often on the scale of 100-1000 times less).

on a side note, when they shrink the chips they change the chip. the changes usually result in more reliable and effiecient chips. companies need to compete so when they change a chip they make it better. this should still aply to the 360 since it means more reliable hardware and less worries for ms.

There are reports that they are adding a second heatsink for the graphics card or something. Still have to return it once, though. Even if they finally fix that problem, they also need to fix the disc scratching problem, where the drive from the 360 scratches perfect discs. You can't get money back from microsoft for those. Their dvd drive is terrible, also being very noisy.

They are finally getting games for their system this year but their hard ware is probably the worst ever in reliability, unless you guys can remember farther back. At least the PS1 you could turn on the side and the PS2 worked for awhile then longer with dianostics for read errors. The PS3 and Wii seem to be doing great as far as failures. I've heard of only a few Wii failures and surprisingly no PS3 failures.
