Well, I took the plunge with MB2TM and bought a Microsoft Trackball. This is the first one that I have ever owned, and OMG I love it. It is so easy to use and it just makes sense. I wish that Apple would make a trackball.
And the pic. This thing is awesome!!!! I cannot ever go back to a mouse now, never. It was only 34 bucks too! Also full X driver support and has been flawless.
m$ generally makes really good hardware for computers. i had a pair of m$ headphones that worked great and had ridiculous sound for their size. any m$ mouse that i have had has been very good and sturdy. they also back up their products with one of the best warranties in the market. the only reason i switched mice was that i got a razer boomslang for my gaming, which is pretty much over anyways.
You know I agree with you Sparkley. I have never had a problem with any of their hardware that I have ever bought. Thank God for Apples sake that they can't get the software down.
