My initial reaction to this glove, Bloody Brilliant.
It will take me a while to set it up just right, but it's very simple to adjust. You can have the configuration software open while using SU and simply add or change the various shortcuts you want on the fly. Once you have configured it you can plug it into another computer and it will retain the mapping.
The glove itself is very comfortable and I am wearing it as I type this on my normal keyboard. The magnetic connection is both strong and easily disconnected.
Ergonomically it is perfect, I have a shoulder injury at the moment that makes certain positions difficult. With this, my hand can sit comfortably on my chair's armrest or on my lap or anywhere I want. It doesn't stop you using normal keyboard shortcuts so you can have your most common on the glove and easily use the less common or number keys etc at any time..
You can program different maps, so you can have an SU one and a gaming one etc etc or even different ones for within SU to match the type of work you are doing.
Have yet to find any Cons so far. I'd recommend it to anyone. It's not that cheap but as a drawing tool it will pay for itself quicker than any higher end mouse or keyboard. It only comes as a left hand at the moment, but they say there will be a righty soon. Wireless would be nice, but it's designed for gamers who want millisecond reaction times, a tiny wireless lag wouldn't be an issue for drawing, but such is life.
