In my house I have a Mac mini HTPC running as an itunes server (among other things) connected to our primary tv. I also have an ATV 1 and ATV 3. The 3 serves the kitchen/living room area and the ATV 1 has been collecting dust in the kids playroom. On the latest software 3.x, the menus are slow and it frequently freezes/restarts. I am considering going back to the 1.0 software assuming it will provide better stability. We only use this for random kids movies on a crappy 720p tv with the built in speakers. The newer streaming options and 5.1 audio aren't really important. Will syncing with the current itunes still work? How about the iOS remote app and audio airplay from itunes? Obviously the easy answer is to wipe it and try it out, just wanted to save myself some time if it no longer works with current apple software.
