Like many Logitech mice, this one feels great in your hand. But the single best feature of the VX Revolution is its overall size. It's a small desktop mouse or a large travel mouse. That makes it the ideal size for people who want to use this mouse all the time. Surprisingly, the small size doesn't hurt the ergonomic feel. It's a little ingenious in that regard.
We could find no downsides at all to the VX Revolution ($55-$75). Logitech has perfected the dual-laser genre.
Honorable mention: If you're looking for full-desktop-size wireless mouse with fewer bells and whistles, Logitech's MX 610 is a good choice. It feels great in your hand, has five buttons, comes in a left-handed version, and costs less ($45-$60). Just don't expect all the software notification LEDs to work.
