I don't have any problem with the buttons. I have had buttons fail me on both my PSR3000s.

Regarding USB pen drives, I keep one on my key chain with a secure but easy to release ring. When I perform with my PSR-S900 at home, it always stays on the ring with the rest of my keys. When I use the pen drive at my job, I take it off of the ring. Since I need keys to get to my job, and since the pen drive is always on my key chain (except when I am performing at a gig), I never worry about where the pen drive is.

This way, I never lose my USB drive, and I am using identical files with both keyboards. When I used Smart Media drives with my two PSR3000s, I had the problem of having different files on each drive.
