We ended up getting the Asus at OfficeMax last night. $50 less than everywhere else.
My wife loves it. She didn't want to go to bed last night because she was still playing with it. The screen is fantastic and the cameras aren't too bad (2MP front, 8MP rear, decent quality in low light). She had lots of apps running and we noticed no slow downs.
Office is a bit hard to use on a 10" screen, but she's not going to be writing any novels on it. She does want a Facebook app, but I showed her how the People app can be a substitute.
I'll post back on here with any updates, but right now it looks like the Asus is the RT tablet to get.
