Zebulon, I had a gtablet a while back, and I ended up shipping it back. Couldn't stand it. If cost isn't a serious issue, I would definitely get something else. I got a refurbished Xoom from tiger direct for only $100 more. Worth every penny, to me anyway.
But if you are willing to put a lot of time into modding it, then by all means, go for it.
Now, I bought another one just to mod it. If it works well I will probably give it to my parents as an anniversary gift.
