I used a PS3 for ages before being able to upgrade my current PC, I enjoyed my time with it and I immagine it would work great as a media centre with that great integration with WMP servers and a great selection of apps (was never used as one though as it was at the same desk as my PC),
But lack of key features and performance made playing games on it a bit of a chore, for instance slow loading times from that slow laptop class drive, Freezing when weird things happened in game,
but the one thing that really put consoles out of my mind was the lack of being able to troubleshoot, the vagueness of error messages, installs messing up and not being fixed after reinstalling (which meant the console needed to be reset), it just became a pain in the arse.
have now sold my PS3 (and my account with it ~11 games digital downloaded) for £130, probably should have sold it for more, my brother occasionally notices my account go online to play fucking CoD, a shame considering there are games like GTA 5, BF4, Dark souls 2, Birds of steel (basically warthunder) installed and progressed through on there.
Also a pro tip for any PS3 users out there: if you have a friend or family member with a PS3 you can activate your account on there console and they can get a copy of any digital games you have downloaded, as long as your account stays activated on their PS3 they can play your games on their own account as if they owned it.
