Android Market now shows which handsets are compatible with each app
With the new feature, those wanting a specific app on their phone won't have to read the text that is posted in the Market. Sometimes longwinded and too much of a hassle to go through, some developers slip in which handsets are compatible with a specific app, but like the fine print on a contract, it doesn't get read. The addition by Google of the device compatibility check will save Market users time and eliminate the aggravation of having to uninstall a recently downloaded app because it doesn't work on your phone.
