I got the gTab and looked at the instructions for rooting. I followed the instructions and it worked. After using it for a while it started force closing apps so I decided to restart it. Once I did that it went into a boot loop. While trying to solve that I found that while many aren't having that problem many are. Trying to fix the problem is much more involved than the original rooting process. I must have done something wrong or there are bad instructions out there because after manually pushing some files to the device it wouldn't even show the logo when starting up.
Thankfully I was able to return the device.
I purchased the Samsung Galaxy and have had a much better experience with that device. While it's certainly weaker spec wise it's a much higher quality device and it comes with the market so there isn't a great need to root the device. Also many of the apps that refused to run on the gTab ran fine on the Galaxy device. And here is the interesting part. Even though the Galaxy tab is slower spec wise its operation is much smoother than my experience with the gTab. Perhaps the firmware has as much to do with performance (or more in this case) than the processor.
If the Galaxy is too expensive or too small for you then I suggest you wait for a different device that will have the android market. Perhaps one of these.

I would get one of these but find the smaller size of the Galaxy is nice for what I use it for.
