I wouldn't draw too many Android conclusions based solely on the nookcolor (NC) because the NC uses a terrible hybrid OS that is part Android and part B&N garbage. I think a true Android tablet or phone will be a different and better experience and comparison. In other words, don't give up on Android based on the NC running the stock software.

If you are technically inclined, even just a little bit, you can create a boot disk using a microSD card and run CM7 (a version of Android built for devices like the NC) and also be able to remove the microSD card and still run the stock B&N firmware. That will give you a much better capability of assessing Android. It will also make for a better tablet which is opened up to much of the Android Market rather than a tiny subset of apps. True Android reader apps are much better than that gosh-awful stock reader app on the NC. It is pathetic, but fortunately there are several alternative Android readers to choose from like Coolreader, FBreader, Aldiko, Moon+ Reader, Kindle, Nook (Android app), Sony, et cetera. Some are really good, others not so much. Even the Android version of Nook is much better than the NC stock reader app! All that I listed are better than the stock NC reader except perhaps the Sony app (which really sucks). By having a few reader apps to choose from, you greatly increase the number of eBook formats which you can read.

I agree that the touch screen is not as responsive and polished as other tablets, but the display from it is very good. The screen is exceptional for reading eBooks, not so much for typing and data entry.
