When is a PS3 not a PS3

Planning on getting a PS3 for the holidays? Make sure you do you homework as Sony is constantly changing the features of the various bundles and models. FInd out your core requirement:

SACD Support:

Only the old 20GB, 60GB and the Metal Gear Solid 4 bundle play  SACD.

Capacity:

Just ignore this. You can upgrade nay of them to a larger drive and probably will need to.

PS2 Support:

Basically, there are currently 2 versions of the PS3 on the market now. 

If you want PS2 backward compatible with PS2 games you need the MGS4 bundle or an old20 or 40GB  PS3. Both backward compatible with PS1 games.

USB Ports:

One version (also the one that supports PS2 games) has 4 USB ports as well as memory card slots, while the new version has only 2 USB ports and NO memory card slots. 

Processor:

The new PS3s do not have the older and larger 90nm Cell processor, they have the smaller and possibly more reliable 65nm Cell processor. Power consumption on this unit is lower as well, dropping from 200 Watts to 135 watts. The end result is a machine that supposedly runs cooler and quieter. Important for movie watching or if you plan to keep it in a cabinet.
