For now, I am sticking with my TF101. A bit long in the tooth, but for what I use it for, it seems to be OK. After getting used to the keyboard dock (with extra batt in it), it is hard to go back. Ditto for having all the extra storage (32GB MicroSD in the tablet, 64 SDXC in the dock).
On related note, Sammy seems to be running into manufacturing issues (capacity ?), device release dates are slippin' left and right.
