In search of my first tablet

I'm looking to buy my first tablet .Going to be reviewing all I can find with the exception of the Ipad . No offense to Apple or to the Ipad . I just do not like the operating system  and the guy really didn't invent the tablet. Gene Roddenberry did when it was put on Star Trek. Ok now that I've got that out of the way I'll be starting with the Motorola Xoom and continue researching new ones in no particular order.
