CarbonCover has THAT problem
I have the CarbonCover case and here is my take:
Positives: 1) Good looking, 2) light-weight, 3)covers/protects iPad well
Negatives:
1) It IS true, this case has some difficulty standing up. Some days it has no problem staying in standing mode, some days it just refuses to stand. Apparently it has to do with the tightness of the "leather". So, it is definitely UNRELIABLE.
2) The magnetic switch (auto on/off) works, it doesn't turn it off when folded all the way to the back like some other covers. BUT, like most/all ultra-slim iPad 2 cases, the CarbonCover's magnet WILL switch on and off your iPad 2 when the front cover is made to slide even if just a little. You pick the iPad up, and you hear the switch click. You walk with the iPad in your hand, you hear the iPad turning on and off. You put down your iPad on the table, and you hear the click. It's pretty bad.
Like most other ulta-slim iPad 2 magnetic cases. Those manufacturers haven't figured out how to implement this magnetic switch feature. Consumers need to really let them know that they need to design their cases so that the front cover DOES NOT SLIDE AT ALL WHEN SHUT, like Apple's Smart Cover. That's the only way to avoid the accidental switch on/off problem. Until then, it's really not a good idea to buy ANY of the ultra-slim magnetic cases for the iPad 2 at this time. Personally I've now come to the conclusion that I need to get the SmartCover if I wanted the magnetic switch in a light-weight case (i.e. Smart Cover + back cover).
So, as much as I liked the CarbonCover (the look and feel), I'm returning it.
