I'm finding that MultiRemote is less choppy than RemoteDroid, so I stopped using RemoteDroid. I also like that on your computer, MultiRemote hides in the tray instead of sitting in the taskbar. But despite all these nice things about MultiRemote, they misspelled the name of their own app - it says MutliRemote when you add it to your home screen.
Neither app is as good as AirMouse was on my iPhone 3g. Shake-for-keyboard was genius, and somehow the mouse was as smooth as the real thing. Gotta keep trying more apps..
edit-Wait... Multiremote doesn't have a keyboard.
