I got my wifi 64 white and it's awesome.
the smaller size has the portraits keyboard just the right size to thumb type and I can do it faster than I can write so I can use it in court (lawyer) to take notes in a pinch, like the other day I pulled out the Mac air 11" and the battery was dead because the kitteh had unplugged it at night, and I needed sentencing notes right then my case being the next to be called. well, have everything in dropbox, all my files, and I installed documents to go on my iPhone 5 and on the ipad mini and I was able t go right into docs to go and open up the word file, and read my notes, and then take notes. it is more useful than my iPhone in this regard, but in a super tight punch the iPhone would have the same document and editing ability, just not as nice a thumb keyboard. so that's my thought on the keyboard
regarding the display, it's not retina like my iPhone but it is 161 pixels per inch or something and that's pretty clean to my eye, about the same as my air,
the screen is very white without color in the white, it's bright,
the device is very thin, and feels very good holding in the hand
in landscape mode the keys in the keyboard are much bigger but I can't type on them as easily as the air and I've fund the keyboard for the thumbs in portrait mode is faster.
I have a folding case and like that, I can have documents open like a PDF or we page of the code and sit it on the desk upright next to the laptop and work with it, so it's useful as a way to display something on the side of the computer.
the speakers are loud and sound good
wifi signal is great
battery life is surprisingly great, seven or more hours and I usually have the brightness on max.
I would only like the home screen to have denser rows for the applications - too much space looks lame
hope this helps those thinking about it!
