The g9 is a very good mouse. I’m personally using full-weight (4 x 7g) and it feels very comfy in your hand. The comfort grip is probably better for photoshoop and other such stuff, where as the precision grip is really good for games.

The g15′s screen is very awesome. I’ve personally got Ventrilo and iTunes hooked up to it, and I want to get the gMod g15 module (anyone got an updated download link?). So awesome, in fact, that when DServ comes back, I’ll be adding built-in support for g15 owners.

But that’s day one.
