I really like it but I think part of it for me is being away from "the computer"; after a day in the office I hate being by a laptop. Twitter is ten times better. Easier for Facebook, showing photos, reading internet heavy content that kindle cannot handle, etc. It isn't perfect by any means but it is quite good. Enough so that I forgotten about an iPad.
I will revisit this opinion when I can get my hands on a HP Touchpad. If it is as synchronized as promised, I might be tempted to switch over for unified notifications and seemless transition from phone, tablet, laptop. Granted my work is moving me to a Palm Pre and HP Elitebook so there is a unified front there.
