Yeah... I broke down and got the xbox 360 over the PS3. But once i am fed up with it, I will go back to Sony. You know, it really does come down to the games you want to play. That ultimatly helped me decide what I wanted get. However, I must say, it was a close race for my hard earned tax return money.
With the PS3 you get the hard drive and the wifi built in. With the 360, you got to buy those two seperatly. $100 for the hard drive and another $100 for the network adapter. OUCH! Now getting the 360, was cheaper. only set me back about $200 and ready to get started strieght out the box.
The PS3 would have set me back about $350. but taking another look at the 360, i will end up paying more if I want the adapter, xbox live and a hard drive. and you will need the hard drive later if you plan on playing a vast amount of games including, your old Xbox games and downloads etc.
Bottom line, if money ain't a issue and you want more games to play, go for the 360. but in the long run, the PS3 is the more cheaper route to travel. Unless, you are happy with a Xbox core system.
