I have a rooted NOOKcolor which makes a great, lightweight, sturdy Android tablet running 2.1 I also can boot Froyo 2.
2 and Honeycomb when I need Adobe Flash or want to try out some of Google's tablet OS features. I am very satisfied with this product and get asked all the time "Is that an iPad?" The great 7in IPS screen (same technology as Apple's famous product) is beautiful and I easily get about 20 hours of use or more from the battery. I highly recommend this product.
