I just got back with mine, 32gb Silver regular size with midnight blue leather case. Pretty pleased with it so far. Whilst the static home button is unusual, it is pretty awesome how easy it is to double click it, hell I can spam the shit out of it without feeling worried about killing it.
Also, from this is my first Apple leather case and I am pretty surprised how slippy it feels. I am hoping it gets a bit more grippy once it gets a bit more worn. After seeing loads of pictures of peoples old leather cases, I can see why they put machined buttons on the new versions, the old ones seemed to look like they lose their shape over time.
