Mouse? Dag...I'm old style...only use the mouse when I'm gaming, on photoshop, illustrator etc...the rest of the time, I'm KB only...short-cuts and Hot-keys
I like doing the Windows Key + E to open Explorer, Windows Key + R to open the Run command, and all other matter of keyboard shortcuts...
Clicking the scroll wheel on my mouse is for F5, refreshing the page. I use that mostly on the message boards.
I like really huge... monitors. Apple came out with one that's rectangular, looks like a movie screen. And I'm really picky about keyboards and mice too, I like my Dell keyboard at work that clicks when I type on it... and I gotta have a scroll wheel.
Other than that, it's all about speed speed and more speed. I don't like waiting for a computer, ever.
Anything that's fast gives me the wood. Hard drives, processors, ethernet, cars, trains, motorcycles (especially motorcycles, they're the only thing I use well at a high rate of speed).....
