Well, Diner Dash 2 doesn't really work on my tablet (Archos 101) either. It starts, but the graphics are somewhat messed up. its still playable and ok for $0, and better than the other free GluMobile game (Poker, which doesn't even load)..
As others have posted, it seems worth it to just add it to your amazon account when its free, then you can decide to download/install it later on your device. Since the AppStore isn't locked to one device (ie I downloaded to my account and can see it on all devices w/ AppStore installed) if I get another phone/etc that supports the app better in the future I'll be able to install it there. That said, I skipped the Shazam app from a few days ago since I would never use it.
