Okay so here's my take on the keyboard. This thing is solid. I mean the build for a tablet keyboard was better than my initial expectation and typing on this keyboard is as easy for me as with a full size keyboard and I have good size hands. There's are no issues for me personal. The mouse is very responsive and I have to get use to not having physical mouse buttons but I have adapted to it rather quick. Yes the battery add bulks, but 1. getting that extra battery with no connection wires and 2. getting two USB 2.0 ports makes it a great add on. Having the original ASUS Transformer, this combo of this is lighter and better compact. Nokia was very innovative in how they designed the mouse to fold as a flap. First of it's kind and different from the usual docks.
I like the shortcut keys. They add usefulness for quick access to changing tabs, putting into sleep and other normal shortcut features. Everything just works. It's also nice than closing the case will turn the keyboard off. Snapping on and off the tablet from the case is nice and simple. I like the pin connectors as it's easier to just load and unload w/o having to slide into any ports.
I do have some cons. First is the mouse fold. Because it doesn't sit flush with the battery, it would seem it would start to tear away at the fold if to much pressure from your palms rest on it too much over a period of time. It's hasn't been a full week and you can see the fold crease starting to form, more particular around the wires for the mouse. I do wish they made a lit keyboard like MS did with the touch type two. I find myself having to use the on screen board at night when I don't want to touch type on the keyboard. I can type quick as hell when typing asdf jkl; but if I want to tap with one hand being lazy, it's hard to see in the dark.
*edit* Another con I have is the mouse tap to wake up the device. I have notice that when putting the keyboard in sleep mode while plugged in that when you close the flap, it can inadvertently turn the tablet back on. It's not problematic for those that have their power setup to turn off while plugged in, but my configuration is set to never sleep while plugged in. To avoid this, I have to make sure that I'm not closing the flap where the mouse is and instead close it by the corner or so.
Other than that, this is one of the best innovative design for a keyboard dock I have seen for any tablet. It reminds me of old school Trapper Keepers.
