Hey, I just posted yesterday about this keyboard in the sticky thread. I think it's pretty good. I used to want the Logitech Mini DiNovo, but could never find myself ponying up the $100 going price. I got one of these with the same as above 40% off (for $36 total) a little while ago and really like it. I think even at that price it's a bit much, but definitely a way better deal than the Logitech.
There are only a few drawbacks about this keyboard:
There are no F keys
Keys are not backlit
Uses a proprietary usb receiver w/ mediocre range (though, it should be fine in the car)
