Pros: Simple, elegant. Hyper-fast scrolling is AWESOME, a must-have. I don't know why more people haven't caught on, maybe it's because I spend most of my time in long pages of code. V550 silver looks beautiful alongside my MacBook. I've never had a trackin
Cons: Has relatively few features. Just the basics. For some people this may be a drawback. (I prefer it this way) It comes with an adhesive hook thing that allows you to hang the mouse on something (like a monitor) when you're not using it, but I didn't wa
Pros: Vertical wheel with wheel that tilts for horizontal scrolling, wheel also can be freewheel scroll or have detents that keep the wheel from scrolling freely) App button (similar to expose' on mac) allows you to see all the open windows on your XP desktop
Summary: This is a great product. Works on various surfaces and I especially like the programmable wheel. I am using it with a laptop and it comes with an adhesive tab that you can attach to the cover of the laptop. When not in use, the mouse attaches to the tab for easy portability. The USB receiver for this mouse is barely bigger than the USB port itself, so you can leave it in without the worry that it will be in the way or lost. Great product.
Excerpt: The V550 mouse worked great. The main function that caught my eye was the ability to scroll through huge Excel files with 1 flick of the scroll wheel. The reason for the 4 rating was the IR receiver stopped working all of a sudden 1 day. Multiple computers would not detect the presence of the...
Pros: 18 month battery life, stylish design, precision laser tracking, nano receiver, USB extension dock and dock clip are included, and the super smooth scroll wheel.
Cons: Scroll wheel loses its third button function, but you can program the button below it to act as a third button, something new to get used to. No darkfield technology like the Logitech Anywhere MX which can be used on glass.
Pros: Wheel scrolls very smoothly, and has enough inertia and low friction that you can spin/scroll the whee completely through a long file with a flick of the finger. Lively and accurate response; simple, beautiful, minimalist design. L/R scrolling!
Cons: No cons really for me. Could use a couple of extra buttons, I guess, for gaming or whatnot--but they would mar the elegance of this fine little device. I think it looks REALISTICALLY futuristic (as compared to cinematically futuristic).
