Advanced 2.4 GHz wireless
Now you can work or play in more places with long-range wireless connection that virtually eliminates delays, dropouts and interference and gives you a range of up to 25 meters (82 feet).*
This is there old model - it doesn't have the win 8 gestures.
I have the win 8 gestures model (T650) and it's pretty good for what it is, but I just never use the thing - a mouse is so much more useful.
The T650 has been available pretty cheap as well - so if you're after a trackpad go with that model instead.
