I'm kind of obsessive about mice. I don't know why, but I have to the perfect mouse with my computer (perfect for me anyway - YMMV). I had tried a handful of corded mice for use on the go with my Samsung netbook: Logitech V100 Optical Mouse for Notebooks - Mouse - optical - 3 button(s) - wired - USB, and the Logitech LS1 Laser Mouse to name a couple.
You see, I do use a cordless mouse for when I'm hanging out in coffee shops or whatever trying to get some studying done, but I wanted a nice, portable mouse with a cord for those times when the batteries got K.O.'ed. I didn't want to use a full-size mouse since it will travel with me in my netbook bag where space is at a premium. I found this little Microsoft pointing device at a local retailer (where I ended up paying nearly ten bucks more than what Amazon sells it for) and am ready to return the other mice. For what its worth, I like the other mice and they are very usable (Logitech makes great devices). But for individual fit, I chose this mouse. Here's why:
1) Size. The other two mice listed here either had a very narrow 'waist' (V100) or was a bit too big to take with me (LS1). The Microsoft mouse is small enough without being too narrow and thus hurting my hand. I use a claw-style mouse grip, and the narrow mouse gave me a cramped hand after prolonged usage.
2) Smooth scroll wheel. I didn't know how I'd like this feature until I was up and running. I dig it - it seems better to me than the 'notched' scroll somehow. I can't articulate it but I like the motion of this scroll wheel - it's not the least bit vague or sludgy. It feels as though it's just gliding in between the two buttons.
3) Ability to customize buttons. The IntelliPoint software 7.0 allows you to reconfigure the buttons, change cursor speed, whatever you'd like. I had issues trying to locate the Windows 7 version of the drivers for this mouse, but a Google search ultimately led me to my reward. All is right with the world :)
4) Style. I'll be honest: if it looks good, I'm going to be proud of it. Call me shallow. My Bluetooth mouse, Microsoft Bluetooth Notebook Mouse 5000 - Mouse - laser - 4 button(s) - wireless - Bluetooth - gray, white - OEM - Reporting, is a sleek, futuristic-looking device that is ergonomically sound and very useful. This mouse is pretty chic too: Mixtures of silvers, grey-blues, a knobby coating on the sides, plus a blue LED 'tail light' all add up to a mouse that looks like a warp nacelle off of the Starship Enterprise (sorry - got a little nerdy there!) The LED light is not super bright, and instead is almost subtle. Very cool looking, I think. It sets it apart from the average black plastic mice I see.
5) The side button on the mouse can be setup how you see fit. I have it as a back button (like my MS 5000) but by default it is a magnifier tool. I can see that being handy in Photoshop, but for me, it was not needed. IntelliPoint has a huge list of tasks you can assign that button - I think I even saw 'Get me a cup of coffee' listed on there as an option when I last checked. Seriously, it's very flexible.
6) Short USB cord length. Some folks may not like the short cord. I love it. This mouse is designed to be used away from home so the portability is enhanced by necessity. Less cord means less to pack/untangle/deal with when sitting in a Starbucks surfing the web. The cord is long enough to wrap around my little netbook to attach on the left hand side of the computer. This still leaves me ample slack to maneuver the pointer. I have a right-sided USB port, too, but plugging in there means I have too much cord to deal with. For me, this setup is perfect; it's like having the freedom of motion of a wireless device without the need to mess with batteries or deal with frequency interference. Good stuff in my book though, again, your mileage may vary.
7) The optical device itself. This is an optical mouse, and not a Laser mouse, or a Bluetrack mouse, or a Darkfield mouse, or a Danger Mouse. That being said, it does utilize a proprietary design by MS that claims to have 1000 dpi. All I know is that this little puppy tracks accurately on every surface I have tried it on within reason (mirrors or glass need not apply).
8) It's a quiet clicker. I know this is picking at nits, but some mice wake the neighbors with the amplitude of their button clicks. This mouse is pretty muted.
If you don't want to mess with wireless mice on the go, this is a great pointing device. It's lightweight, comfy (for me anyhow), good-looking, and very accurate. I realize MS in the past has made inferior mice, but this and my Bluetooth 5000 are changing my mind about them. Good luck!
