Xbox 360, because you can get everything you can get from a PS3, except the Blu-Ray player (which nobody gives a crap about anyways...) for only $200 and it comes with the internet cable and accessories. Also Xbox Live is x1000 better then PS3 Live (or whatever you call it) will ever be.
There are about 30000000 topics like these you should read for once. Also, dont just place your opinions but some arguments would be good too.
The 360 is cheaper and has better games and internet, but it's quite fragile. You should be carefull if you have a 360. You should also get in touch wiht the games you want, because the games i prefer are mainly on 360 (halo, guiater hero, saints row and ninja gaiden)
Ps3 rules. So what if xbox 360 has a slightly better online system, you have to pay for all the good features. Ps3 online is completly free. So what if some of the games are better ps3 is getting some very good family games like littlebigplanet and resistance 2. Also xbox 360 suffers from problems like rings of death while ps3 never suffers from these types of problems. Also ps3 has the cheapest blu-ray drive on the market. The price tag may be a bit much but it is well worth it.
