Aw, I can't believe anybody could hate sony's game boxes, I guess I just don't see how the smaller boxes would be a problem when organizing them and the vita boxes are freak'n adorable! :D
As for going digital, I still love collecting, and I just don't see too many pros for doing it besides reducing product waste but the smaller boxes are still helping with that.
Because what if in future something happens to SEN, say Sony launches a brand new service. You probably won't be able to continue re-downloading your games or it'll probably still cost you at a "discounted price".
The same thing with licensing, any game you paid for could eventually be pulled from SEN/XBLA and if you don't have it downloaded then it's simple "hey, sorry about your luck".
With all that, the 10% discount just isn't much of an incentive at this point, especially with the price of all the memory cards you'll need.
