First impressions after a couple days...
1) It IS smaller than the standard iPad (duh). The impression of smallness was to some extent exacerbated by the fact that for the last couple of weeks I've been using my 15" MacBook Pro.
If used mainly around the house, I think I'd prefer the larger. In fact, rumor has it Apple is considering a "Maxi-Pad", though I hope they call it something else.
But this is my plane/traveling device, so I think the choice to go with the Mini was the right one.
I have gotten into the habit of double-tapping the screen to zoom in a bit before trying to hit a button or link, which makes it comparable to the larger screen in level of difficulty.
2) It IS sharper - I guess. With my aging eyes and looking through smudged $1 Sav-A-Lot readers at a normally smudged screen, I don't see a huge difference. YMMV, but I never found anything wrong with the iPad1 screen in the first place.
3) It IS fast! Especially loading web pages. Nice.
Only problems...
1) I was trying to download the large pdf of the FAA's "Flight Training Handbook", to save to iBooks along with "The Pilot's Handbook of Aeronautical Knowledge" and maybe a couple others. Hangs up about half way and crashes Safari.
2) Went to stream "Dancing With The Stars" to our Apple TV yesterday, and got little "hitches" every 10 to 15 seconds. Restarting both devices made no difference. Played fine through my wife's iPhone, so I don't think it was the program.
Anyway, happy so far.
And Jake, at least, seems to appreciate the higher resolution:
