It tracks on glass, pairs with a mini usb dongle that also operates a companion keyboard (1 receiver for 2 devices) and best of all - the scroll wheel has two settings, normal click wheel and free spin. You can flick the wheel and let it fly as you scroll to the top or bottom of web pages, pdfs and any other lists on your pc. At $50, I think it will be the last mouse you ever buy. I have 3 Of course, I power it with rechargeable Sanyo Eneloop XX AA batteries and get 4-5 months of daily use before a recharge. $18 I also run the compatible wireless keyboard when my laptop is docked to those big 24" 1080p montiors. The Logitech Illuminated Wireless Keyboard K800 is an awesome keyboard and I have one at home and one at the office. Powered by those ULD (ultra low discharge) eneloops, I get 3 months before I have to plug in with the included usb charging cable. The illumination comes on as you approach the keys with your hands and dims to off as you move your hands away... $75 The above makes a great work solution and I can't see myself using anything else in the foreseeable future.
