Well I bought a PS3. Here were my reasons:

1. Gran Turismo 5
2. Metal Gear Solid 4
3. Final Fantasy XIII
4. Blu Ray Player
5. Linux/Crunching/HTPC thingamabob

I mean... seriously, GT5 and MGS4 are going to be THE pinnacle of ALL gaming in 2008, be it console, PC, whatever. And yes, that is just my opinion.
