BN just released the Nook Tablet, seems very cool! I previously owned no e-reader, just got an iPad. Is it good idea to get the NOOK Tablet for $249 now? http://www.amazon.com/gp/product/14...17145&creative=399373&creativeASIN=1400532655 Or wait for a week to get Kindle Fire? Not much difference between the two right? except the price?
