The n810 is an alternative kinda. Put it together with a Wiz and an 160 gig ipod and you're set! That combo is also approximately $700 dollars. And a lot less portable.
I got my Wiz for Christmas, just started playing with it. Got the SNES emulator running, but couldn't find the one file to make it work well. Its an amazing device, sad I didn't hear about the pandora sooner. Just might get one anyway.
