Putting one on my Christmas list - I've heard the Brookstone one is good, but have been reading some threads on the Zaggmate too. Also saw the Kensington on Amazon for $59 - down from $99 and it looks like the Brookstone one.
A few things that I'm considering...
I want to be able to use the ipad in the case without using the keyboard - may not always use the keyboard, for instance, taking a few min in a Starbucks to read, etc... The Zagg looks like it is just for using it and won't fold back to use without removing the keyboard. Correct me if I'm wrong.
Zagg says they have shortcut ipad keys as does the Kensington and both seem to support using portrait or landscape... Brookstone doesn't mention shortcut keys (i.e. Home button)
Thanks in advance for your feedback.
