Plus the main processor "cell" is brand new ....... there is not older version ..... so first it needs :
1 - A compiler
2 - ressources
3 - a linux that works on it ......
better to go to buy a dvd player with divx and other codecs enabled for 40$ .....
or even build a media pc ...... it will be cheaper than a PS3 .... And it's already there.
Don't mix the power of a PC and the PS3 too .... the purposes aren't the same and so the design ..... PS3 will be never more "powerful" than a PC (and a PC will never be more powerfull than the PS3). The use is too different .....
for example ......
Let's say the example of graphic cards ...... a single 600 Mhz GPU is sufficient to lay down any actual processor in terms of 3d .... Why ? because it's optimised for it ..... the intel or amd processors are all purpose witch is not the case of a gpu processor ..... so the gpu will loss in any domain other than 3d .......
The same thing is true with PS3 witch is not a PC and never will (if it does, better buy a true one).
Sony claims that PS3 is a PC in order to lower the VAT over his product (in some country the VAT is lower for PC than console)
