So I'm in the market for a new mouse, but I'm not sure which to get. I used to be a gamer, mostly First person shooters, but not as much anymore, but I was going to play a little here and there. I've used an MX510 for years so I don't really see the need for the 2000dpi and what not of the G7. But i do like the shape of the G7 (since it is very similar to the MX510). I can get both of them for around $40-50, but can't really decide. Please no, its personal preference responses haha I know that =D. The MX seems to be a big favorite on these forums, but I'm still not fully convinced. Other thing is the battery life. The swappable batteries on the G7 are nice but I hear they only last about 2 days each, while the MX i heard lasts about a week to 10 days. The only thing i dont liek is that you need to use an Outlet to plug in the charger for the MX not a USB port but thats not that big of a deal. And last thing, I've seen some posts on the MX about a "previous" version of it. Are there major differences between the previous and the present generations? THANKS!!!
