The cheapest way is to buy an XBOX 360 and GTA, most people dont care about wanting to run linux, blue ray, they may just want to play the damn game...
Maybe the PS3 is better but until they actually have a bunch of games that are actually better then the host of titles on the 360 its not worth arguing about what could be in the future if a bunch of developers actually manage to produce anything original, next gen and PS3 only.
@Home - Delayed
GT5 - Delayed
Metal Gear - PS3 cant handle what we wanted to do...
Thing is while people may say that the PS3 is truly next gen, I have been playing next gen titles on the 360 for 2 years+ now. Its never overheated, failed, ring o lights etc... The games GRAW, Dead Rising, Forenza, Gears, Bioshock, Mass Effect to name but a few have all been amazing, the online is solid and worth the £20 a year for play, demos and vids. If Microsoft could handle other parts of the business like the 360 they would be on a winner.
The PS3 was late, expensive, hardly any original games, 360 ports, usual EA stuff but it does have blueray! An obsolete format, we have this thing called the internet now, movies dont need to come on disks, same way as music doesnt need to come on tapes.
