I'm loving my Tab. I own a 3G 64G iPad and the Tab is far better in my opinion. Browsing is fine if you avoid the vileness of Flash, once you hit that it seems to slow down.
The battery life is nice, as good as the iPad which seems to last and last and last. I've been playing with the Tab all night and through this morning. It got to halfway from no charge after I bought it after about 4 hours.
The Verizon version, I can't find a way to activate the camera on the front. I guess since you can't make calls they disabled that. I'm still looking, why? Because I paid for it, so I must turn it on!
Speed and performance are nice, I have a Droid Incredible so I miss my HTC interface but the standard Android interface works for now. I'll keep the 3G option active, that was the best feature of a tablet to me. I can be anywhere and never have to worry about not being connected. What's the point with just WiFi...
I like the calender and email views. They'll do though I know I'm going to want to change their look sooner rather than later.
And, I pad over $1,000 for my iPad - TOTAL WASTE OF MONEY. I paid $600 for the Tab and it's been worth every freaking penny.
