No, computer mice.
I seem to have had nothing but trouble after trouble with mine. The lovely little laser mouse I got with this lappy died on me a while ago, after having no problems in the two years or so that I had it. I had to have one nearly twice the size as a replacement, which took a bit of getting used to. 🙁
My brother’s was exactly the same when he had it, but for some reason his took like an extra ounce of pressure just to click. It’s a wonder his index finger didn’t become a professional wrestler.
Then, the one I got after my first one died developed an utterly insane problem. It would unclick in the middle of a prolonged click (making click-and-drag selection virtually impossible), or outright fail to click at all. This was so frustrating for me, I slammed it against the work surface in a fit of unbridled and unjustifiable rage when it misbehaved, which probably made the problem so much worse. At the time I was working on my Music Tech A2 project and I think I might have gotten a few odd looks from my classmates when this happened.
I’ve had horrible luck with mousemats, too. The one I’m using at the moment is fine, but I can recall being virtually unable to move my mouse around on it at some point. Might’ve been a problem with the mouse, but it sure “felt” like it was the mat’s fault.
Most recently, my current mouse has been playing up in ridiculous ways periodically. The left-mouse button and the middle button will sometimes click twice. If I’m moving the mouse while it happens, it will often click in two places at once simultaneously. If I’m opening a new tab in Firefox I’ll get the same one appearing twice – sometimes even three times.
Throughout the worst spells of this technical nightmare, mapping for Doom becomes nigh-impossible, especially when selecting several items at once – things will be deselected randomly, or a window will pop up when it’s the last thing I want, and it likes to select things I don’t even remember moving my mouse anywhere near. Browsing on the internet becomes frought with paranoia because whenever I click a window away, whatever is beneath will also be clicked (sometimes twice) – a couple of times now I’ve accidentally clicked on ads, which is of course a stupid thing to do. I become so paranoid due to the arrogant behavior of my mouse, that when I make myself sandwiches, I get the irrational and horrible feeling that my finger is going to click on the bread twice and it will end up clicking a popup underneath or something.
Also it likes to do exactly the opposite and cut out randomly, or just slow down for a few seconds during a crucial game or at a point where I need to move a window critically. Yeah, thanks there, buddy. ^_^
Also fuck Mac mice. What the hell’s going on there.
