I have not 1 problem with the wireless controller, they last for maybe couple days and take a very short time to charge, unlike the xbox replacing batteries is a pain. The console itself is fine though there sometimes is a short delay when accessing things in the XMB. I reckon the XMB could be improved in speed and also design.
I fucking hate when you have shit internet and you download something that's 17GB and then it gets to 14% installation and feels to tell you that there is an error..
Wish they could point out mid download that something has happened and then do it again.
I hate that there are amazing PS3 games that were never patched for trophies, like COD4, GRID, DiRT, Heavenly Sword or Marvel Ultimate Alliance, just to name a few.
