83g is too heavy?? What weight would be ideal for you then? =)
Anyhow, ty for the article. Looks like an excellent mouse, same weight category as the g-302/3, with a more comfortable, pragmatic shell. Logitech maybe wanted to create a simpler mouse with the G-Pro, reliable, hopefully with little to no sensor rattle, that could work fine with or without software. Maybe they're starting to understand that using odd shapes for some of their mice isn't necessarily an ideal way to distinguish themselves. Ditto re software. Some of the best selling mice don't rely on proprietary software, which isn't necessarily a bad thing.
The g502 Spectrum is on the heavy side, and while it's likely the best mouse for browsing on the market, I find I rarely use mine, even for browsing, Not because it isn't an excellent mouse, only because I'd gladly forego it's features, and settle with a 3310 optical sensor if it means being able to use a mouse that is far more comfortable to the touch and to use in general. If the G-Pro had been available at the time I got the 502, I'd have gladly gone with it instead.
