can't say i have had any bad experiences with mine as such, yes it can be alittle slow and laggy at times but i will say having bad experinces with their N900 i wote for this user.

for me it's still a matter of knowing your hardware, like know your car, not going to belive that your stock Fiat 500 is going to be the ultimate drift car...

EDIT: just to be clear i don't have a Fiat 500... that would be the day the rest of my mind melts, only rear/all wheel driven cars for me
