Update: Great news -- we ran the Cloud Player on an original iPad and iPhone 3GS without a hitch. In fact, there was very little (if any) lag or time delay when buffering a new song, and were able to refresh playlists and other information quickly. The interface of the Cloud Player is almost the same as -- if not identical to -- the page that loads up on your computer browser.
Even better, the Cloud Player works flawlessly with the multitasking controls in iOS; the usual forward/pause/volume options are all usable as you play Angry Birds. Sadly, there is just one bump in the road that keeps the process from being perfectly smooth: mobile Safari prohibits you from doing drag-and-drops, which adds a couple extra steps to the process of adding songs to your playlists. Take a look below for some screenshots of the Cloud Player in action.
