Logitech G5

Logitech G7

Both look really pretty. The hotswappable battery packs of the G7 is a really cool idea as well. The only thing that worries me is that they claim internet forward/back buttons, but I only see a back button in the pictures. There's also talk of the MX610 coming around the corner...

wow very nice, i own the mx510 and love it. Logitech continues innovating and making the best mice. Adjustable weights and the Polytetrafluoroethylene feet are great ideas.

Bad:

Full-speed USB + 2.4 GHz cordless

4X faster than conventional mice, USB delivers blazing speed and instant acceleration. With a 5X** stronger connection, 2.4 GHz wireless "bulletproofs" the G7 against lags and interference dropouts.

This will interfere with WiFi connections.

Not necessarily. Wifi bands are actually 2.412-2.484GHz (depending on where you live). Most cordless phones actually lie just under 2.4GHz.

The term "2.4GHz" is just a name for a frequency range that companies are allowed to use for wireless data transmission. With proper setup, you shouldn't get any intereference.
