Go to details and look at the specs. Some have HDMI, SD, Micro USB, USB, and other stuff, while the others don't. They are not the same thing entirely, but they are the same core components. I was thinking about the refurbished one, but isn't refurbished old hardware? Not old as in 5 years, just as in a used condition. Wouldn't it break faster and have cosmetic blemishes?
Edit: I've been reading through the Asus's reviews. Yeah, I'm gonna go with the Iconia.... Not considering the ThinkPad anymore because it lacks any effort of trying to get me to buy it, and the reviews aren't that great, either.
