For those that use both, Splashtop currently does not work with Lion. The iPad will still connect to your computer, but all you can see is a blank screen. I have talked directly to the Splastop devs and they are working on a beta version.
So if you have to use Splashtop, I recommend holding off upgrading to Lion.
