Purchased this sleeve looking for something to protect my Surface Pro with the Type Cover. It's a little snug to start with, but loosens up over time. It's also deep enough to leave the stylus attached and protected. It's also stiff enough to ensure the power button is not accidentally hit while in my bag. Overall, the best sleeve for the Surface I have found. I can't recommend it enough.
PS. The Surface Pro 3 with Cover also fits in the sleeve, but its a little tighter being a few millimeter thicker.
The sleeve is beautifully made out of heavy duty materials--as expected. And it works great with my Samsung tablet. Just like my Macbook Pro case works with my HP laptop.
I guess it would be ok for an iWhatever, too.
