Just to let people know (users, delevopers, whoever)...be careful with the Karma. I'm sure what I experienced is a rare thing, but my Karma is already unusable less than 24 hours after receiving it. I must have bumped the player against the wall while it was in my pocket, but the Riostick and the scroll wheel now don't function much. When I spin the wheel, it spins off track without the notched feeling and the Riostick moves around. The wheel also gets stuck and I have to push hard to free it. Basically, the navigation is gone. I don't abuse electronics, but I expect them to take normal bumps and the stuff that my 3G iPod took with no problem. Anyone else have problems with it being this fragile? I've got another Karma arriving on Monday from BestBuy (me ordering from too many places), and I'm not sure if I should give the Karma another try...I'd sure like to though.
