Go for it. I've got a
targus Mini Mouse. Fits great in my case and easy to travel with. I just turn it on and use it. I've had it about a year. I bought and returned a Microsoft, Logitech, and some off brand I found at CompUSA.
A couple of items to keep in mind when buying a wireless mouse:
- Size and Weight - Especially if you travel
- Battery life - Can it make it through an eight hour day?
- On / Off switch - Extends battery when not in use
The targus will last around a work week on a couple of triple-a's. That's 8-9 hours per day. I carry a couple of spares with me just in case I accidentally leave it on. (which will eat some battery, but not all of it) Sooner or later, I'm going to buy a set of rechargeable for my desk as I'm traveling less, but the cost justification is right on the border: ~ $25 for rechargeable or ~ $12 for 6 months worth of AAA's.
I do not know about gaming performance, because I don't really game with this laptop (i6000 and E1505). No lag that I can detect, however. Good Luck!
