Long winded sometimes but an excellent guide to understanding shutter speed. I also have Understanding Exposure (also by the same author) and have used the online resources to greatly improve my ability to photograph creatively.
Just got this so thought I'd write a quick review.
Wallet has a nice, simple, ergonomic design. Xoom fits nicely and feels well protected. Wallet works well in the standing and slightly raised typing positions and looks great closed. All the port holes are in the right place and build quality looks good. Funny and odd thing is that you will put the Xoom in the wrong way round first time, it needs to go in upside down. Makes absolutely no difference as Xoom screen will auto-rotate and actually makes sense when you think about where the flap would be if it went in the right way round. Would recommend without hesitation.
