I've gone through a couple of cases so far. Here is my experiences on the iPad 3 or iPad new or whatever you want to call it.....
My first case was the Speck Pixelskin HD for the iPad 2. Case fit the new iPad very well. was actually quite happy with it until I saw Speck had the new Pixelskin HD designed for the iPad 3....the only thing I didn't care for on this case was the gummy strip to keep the cover closed.
Speck then put out the newly designed Pixelskin HD for the new iPad. Sleep/Wake magnets, newly designed clasp. I ordered it. Not so impressed. Sleep/ Wake function worked great, however the case itself fit a little looser than the iPad 2 case. New clasp was OK, but let a small gap between the cover and the screen. Since I throw my pad in my bag a lot I didn't like the idea of having a gap that allowed junk to gather between the screen and the flap (I'm currently going naked...no screen protector). I sent it back to Speck....they have an awesome return policy...and ordered up the Speck Fitfolio.
Speck Fitfolio...So far I really like it. It has a plastic back with the proper cutouts for all openings and Vegan leather (pleather) front that wraps around back, Sleep/Wake function works great, newly designed clasp (not the bungee like on the older one), NO GAP between screen and front flap, inside of flap has soft microfiber lining (seems to collect lint). It folds into typing stand or viewing stand which I really haven't used yet so I can't comment on how well they function.
So for now I will be rockin' the Fitfolio. I really like the fit and function, it looks stylish, and doesn't add too much bulk compared to other cases. I will have to see how she wears...only time will tell. YMMV
