Dflat's response is quite thorough. I would add this caveat regarding screens: Most cheaper tablets will have a "TN" (twisted nematic) display, which gives high brightness while using less battery, but has a limited viewing angle. My first tablet purchase was TN and, when I move to the left or right, the image fades. If this will be a concern for you, I'd recommend springing for an IPS display, especially if you're accustomed to Apple's monitor quality.
