I'm still holding onto my n770 and installed the hacker edition of OS2007 to hold me over. The only advantages I've heard are the 2 slots, and faster (as in a few seconds of loading) processor. I hardly run multiple programs, so the 770 is fine for now. Plus, I REALLY like the hard cover.

I wonder if anyone has done a battery drain shootout between the 2 tablets. Seeing how the 770's processor and memory is more anemic, it might stand to reason it drains the battery a little slower.
