Hello.
I recently purchased the Logitech MX1000 and thought I'd give my feedback.
First of all, my workspace isn't very big, cords have been an annoyance as long as I can remember. Long ago I had a cordless ball-mouse which broke, leaving me with a cheap infrared corded mouse because I didn't care enough to buy a better one. Well, I was at the local Best Buy and the mice caught my eye.
I was originally looking at the MX510 because of all the good reviews, but again, I didn't want to have a corded mouse anymore. I had also heard some bad rumors about the MX1000 so I decided to buy it and see for myself.
First of all, the videos showing the MX1000 cursor dead during a "U-test" weren't accurate for my MX1000. I've tried to replicate that test in wide Us and very steep, almost Vs (which of course would never happen in the real world anyways) and yet I couldn't achieve a dead cursor no matter what I tried. Either the video creator had a defective/abnormal MX1000 or else they fixed the problem in a newer revision. That out of the way, this mouse is extremely precise, as far as I can tell. No erratic behavior, and very fluid motion.
This mouse has a nice look and feel to it too, and when you do as much editing/gaming as I do with a mouse, you'll really appreciate the design. Notably, the thumb rest is low enough to avoid accidental button presses and high enough to quickly press them when you need them. Feel is definately important to a primary input device.
I don't have any complaints with this mouse.
