Pros
Pro High quality build, very durable
This mouse is amazing quality for the price. The trackball is smooth and precise, and the mouse feels very well built/durable.
Pro Good battery life
Logitech promises a battery lifespan of 18 months off of a single AA battery.
Pro Charges by micro USB (power usage appears efficient, too)
Plug it in to a MicroUSB cable supplied with power to begin charging. Seems to charge relatively quickly and last quite a while.
Pro Full touch surface (horizontal, vertical)
You can use this just like a laptop's touchpad for the most part, albeit with an obviously smaller surface. Drivers/apps are available for both the Mac and Windows versions of this device. The black one is targeted at Windows, and the white one at Mac OS X users/computers, however they're the exact same thing. If you have the black/Windows mouse but want the app/drivers for Mac OS, use the T631. If you have the white one and want drivers for Windows, find the downloads for the T630 (this one) on the Logitech website.
Pro Pair with up to 2 devices, toggle between them with ease
There's a switch on the bottom that you can toggle left/right to tell it to which paired machine you should be sending input from that mouse. Pairing works the same way - just shift the switch to the left, pair it, then to the right and pair it with another device (computer, tablet, etc.). Then to toggle between those devices, just flip that switch.
Pro Bluetooth
Wireless via Bluetooth
Cons
Con Learning to use the thumb to control the trackball might take a while
Most trackballs are finger-operated, and learning a new to control the mouse might take some time.
Con MicroUSB charge port is on bottom of device (no use while charging)
You wouldn't be able to use this while charging because the only port into which you can plug your MicroUSB cable to charge is on the bottom of the mouse, below the laser used to track object movement.
