Have you tried Splashtop HD on the Prime yet? It is on sale right now for $6.99 I think in the android market and it is absolutely amazing.
I have Logmein Ignition but it doesn't even compare when it comes to smoothness and even usability. I am a photographer and I just used Splashtop to load up my desktop computer that I am away from and was able to fully use Photoshop to design an album for a wedding couple right from my Transformer Prime. It was a thing of beauty. They keyboard dock lets you use photoshop keyboard shortcuts and everything. I can't even begin to describe how awesome that is!
