Something like this:
Moxier Mail -- Incompatible because of resolution problems. Dev says it'll be fixed in upcoming upgrade.
Mizuu Movies -- emailed the dev, he said he should have support for smaller screen tablets ready around mid-November. (If you guys haven't seen or tried Mizuu Movies, you really should. It's phenomenal.)
Reddita -- about to email the dev (he's an XDA member) and see if he can help us out.
IMDb -- resorts to the phone version of the app, rather than the EXCELLENT tablet layout.
Movies (Flixster's Rotten Tomatoes app) -- installs but force closes on our small resolution tablets. (An excellent tablet app on the 10.1 inch Honeycomb tabs, though).
Feel free to add away!
