A photo leaked in Asia shows the iPad 3 case getting measured with a caliper.
The rumors have already said that the iPad 3 will be thicker. Now a photo has appeared that shows exactly how much thicker the iPad 3 is than the iPad 2. The iPad 3 case measures in at 9.5mm, which is 0.81mm thicker than the iPad 2. The difference is less than 1mm if this photo is actually legit.
0.81mm is definitely in the realm of what Apple would accept as compromise to offer the same battery life time on the more power hungry iPad 3. Long battery life time is much more important than an almost unnoticeable thicker case.
We still expect the iPad 3 announcement on March 7th.
