LoboBlanco: ...since you want more accuracy, I should say that a laser mouse is as accurate as an optical mouse (I have both), it all depends on the engine they use, if they use an engine with same resolution and poll rate, then there´s no difference besides the kind of surfaces they would be able to run on reliably.
korell: All laser mice have some inherent 'acceleration' even if it is turned off in the settings. It's to do with how they work. Hence why optical mice are more accurate, especially when it comes to first person shooter games. Though the very top end laser mice massively reduce this issue to the point where it can be hard to detect.
LoboBlanco: Ideally you shouldn´t move your hand too much if you correctly set your mouse speed, so smaller size mousepads should do the trick, bigger ones are usually meant for people who swing their arms like crazy monkeys but those are ok if you want to use part of them to rest your hand :P
korell: This is actually a user preference. I know many who use very low DPI and sensitivity so that they have to move their whole arm large distances. Why? Because they can then target down their sights in FPS games with the smallest of movements with little mouse movements and are still able to spin around with large mouse movements.
For me, however, with such limited desk space I only have about 20cm left-right movement space, so I tend to use a setting that allows me to cover the distance of my screen resolution in those 20cm.
I was speaking practically, technicalities don´t always translate to real world perception awareness.
In the same way a 3.1Ghz cpu is faster than a 3.2Ghz cpu yet, in the real world it just doesn´t matter unless you have the perception of a fly :P.
Although I understand some people like to swing their arms across the desk for their own purposes (I used to do that with an Amiga mouse, not because I liked it but because of the low speed at the time), I was talking about the ideal setting which doesn´t correspond to people varying tastes but healthy recommendations :P (If you´re not playing CS, there´s no point in the swinging setting). Personally I just change the dpi on the fly for long distances and back to high dpi for fast reaction.
Anyways, 20cm is way, waaaay more space than you´ll ever need for either use. At least on my settings I can cover my screen in just a few centimeters and yet I can have pin point accuracy (I have an extremely steady hand though :P) with such settings.
