Generlly I have been impressed with apples design - until I got the official case / cover for my iPad.
When it's on you can't put it in the official apple dock.
Well, I mean I can now, but only as I got someone with much steadier hands to modify it with a razor blade.
I find my iPad much easier to use (from an accesibility stand point) than any other pc in the house.
Unfortunately I don't see android doing anything near as good in that area yet. Windows is catching up with mac os on the built in accesibility though which is a good thing.
But (as much as I hate to admit it

) - my old mac that I got given which is what 5 plus years old is still better at zooming and screen reading out of the box as it were. Same with my iPad.
Now as odd as it sounds I can use my ipad with the screen completely off and I get on brilliantly with it and obviously as the screen is off the battery lasts a silly long length of time.
I know I got it for christmas and would not be able to afford one but I think the only reason I do like it so much is as it does fit a specific need for myself.
Anyway that's just my 2p and all that
