I just decided to buy one a few days ago, now that it's at least $100 less than when it launched back in Sept. I'll say that it's pretty light and thin, but should open up to a wider angle for viewing. It has 2 USB ports for a mouse, etc. but does not seem to work for anything else like mounting flash drives or anything. The keyboard feels comfortable and the touchpad can be quickly turned on/off with a couple of taps. It plays movies pretty well, has stereo sound, and looks good but does not work with NFL mobile just so you know, but it does work great with sites like Hulu for TV shows & movies.
It gives you a low memory error if you open too many tabs or windows at one time which drives me crazy. I usually keep 11-12 tabs open in Firefox on my desktop version but found that I could only keep about 4 open for a while on the Lapdock before getting the low memory error again which will shut Firefox down causing you to have to re-launch it.
It also has it's own version of Firefox (a desktop version) so it allows you to surf as a desktop machine instead of a mobile device. This was one of the things that peaked my interest because it makes it much easier to directly install some third party apps from web pages that block mobile devices from downloading.
One thing that's also really nice about it is that it has a long lasting battery and whenever the phone is docked, it's also being charged, so you know that your phone will always be 100% charged when taking it off the Lapdock...making it a very nice (although expensive) charger that plays great movies and surfs the net.
Therefore, overall I would rate it about 7.5/10
***Correction - USB Flash Drives CAN be mounted depending on the formatting***
