I have a tab, and I think it is great. I understand that other tablets are coming with Honeycomb, but so far, the GTab has been a great product for me. I use my tab, and LogMeIn, and I don't even carry a laptop anymore.
The size is perfect for portability, as I can literally put it in my pocket when I go somewhere.
I am not one who is always looking for the newest and greatest thing, so the tab, though some say is "obsolete," works very well for me personally and professionally. I use it for email, movies, facebook, twitter, internet, and like I said previously, I use it in conjuction with LogMeIn, and can remotely access my desktop computer at work.
In regards to your comment about rooting, I am not rooted, but I believe there is another thread that says the last update released to the Tab prevents z4root from working. SuperOneClick is a way to do it for the time being. Check some of the other threads here and you should find your answer.
Good luck... I hope you enjoy.
