My misgivings are;
4.5 hours to recharge via USB 2.0
90 minutes of battery life / charge
you can't fold the keyboard flat or compress it with anything heavy.
Might be reasons that I end up taking it back.
Umm, that is 90 HOURS, not 90 minutes. Significant battery life on this little guy for a 4-5 hour charge, which I typically do while at my desk using a laptop (which has its own keyboard).
As for folding it or compressing it, so far, I have been carrying mine around smashed up in my laptop bag, cramming it into overhead compartments on planes and such, without issue. For me at least, it has withstood a lot more abuse than my (excellent) logitech "hard" bluetooth keyboard, which I eventually broke (but got another because it is a great keyboard too). I guess if you are looking for something indestructible, this is probably not it, but it has been pretty durable for me.
The two things I DONT like about it:
1. Cant get the software to activate (I assume it is only there to supress the on-screen keyboard)
2. The little "cap" that covers the on-off switch and charging port is easy to lose. I still have it, but I am sure I will eventually lose it. It should be attached somehow. Once it is lost, I will no longer be able to type underwater, and will have to find another solution to my underwater typing needs.
If anyone has a solution to the software activation problem, I would really like to know about it. If someone has a solution to the underwater typing problem, well, you lead an interesting life.
