| As do I. And I hates it. Worst mouse/keyboard combo ever. However I upgraded from the 5000 to the 5500 last weekend and I'm pretty happy with it. I still think it's stupid that my old MX700 tracks better when I use it on my couch than the 1000 or the Revolution. Must be something to do with optical vs laser. Even if I use a mouse pad the Revolution is at best mediocre on the couch, must be something to do with it not being a hard flat surface. I can use my 700 on my goddamn leg or arm and it works great. |
