The 40 GB uses the old 90 nm chips, and runs a bit hotter and eats more electricity than the new 80 GB SKU that uses 65 nm chips.  It may also be packed with the sixaxis rather than dualshock 3, but I am not certain of that.  The other features (or lack there of) are the same.  The upcoming 160 GB SKU is the same as the new 80 but with even more storage.


do research first next time the 40GB uses the 65nm chip
