We can have three types of sensor, mechanical, optical and laser. The first one is pretty much outdated nowadays, and it is only used on trackballs, still you might remember back in the day where your mouse had a plastic ball underneath, that ball would then move two or three rollers inside the mouse, and that would trigger the movement. This old technology had problems, would only function correctly in a very smooth surface (mouse pad) and collected grime and dirt from the surface, eventually you would have to clean the ball and the rollers, and you would notice an immediate improvement on precision.
What you can see in stores as far as mice go are the optical and laser sensors. The optical's sensor superiority regarding the mechanical is notorious, since it is more precise because of the light based sensor, does not collect grime/dust, since the sensor itself has no contact with the surface. The colour of the sensor light is red, just because it is the colour that takes less power to produce, if any other colour was used, it would just battery usage. It poses no threat to the human eye, since it is only light, but not all is roses, it will struggle with surfaces that are not even, or have a heavy texture and also glass, so you will not be able to use this on your leg, and should stick to non glassy desks. If you want decent precision, this sensor will not let you down, as it goes as far as 1000DPI in some cases, and you really don't need more than that for most computer applications.
Now the laser is a different story, same principle as the optical, but it uses a laser to do so, it is a lot more precise, as it can now reach up to 4000DPI, uses even less power as the optical and has no trouble with rough or uneven surfaces (some can even work in glass desks), the only downside is that you shouldn't point the sensor to your eye, since it works with radiation that could pose a problem. A few years ago i would say you should only go for a laser if you work in Design/3D or a first person shooter gamer, since all these applications need a lot of precision, but nowadays the price between optical and laser is roughly the same, so I would advice you to shell out a bit more and get the best possible, specially if you are using this in a laptop, because often we like to use the computer in bed or in other less standard places, and a mouse that can deal with rough surfaces is a must.

Power Level Gauge
This is a cordless solution, so it uses some sort of battery, some user regular AAA ones, other use internal bateries, but on thing is certain, at some point they run out of juice, and that can happen in the worst of situations. Luckily that hassle can be avoided if you choose a mouse with an indicator that lets you know how much battery life you have left, and trust me on this one, this is not one of those features that nobody will use, you will need it eventually, as it would be like using your car without a fuel gauge.
Scroll Options
I'm not even going to cover the mouse without a scroll wheel, because those just don't make in sense nowadays, still has far as scroll wheels go, we also have some different designs that will or will not fit your need. The basic wheel only moves back and forth, enabling you to perform a vertical only strong. Another type of scroll, that is nothing more than an advanced scroll wheel, allows you to use the wheel to scroll and also to perform a click, just like a button. The last innovation in this department is the use of a small ball, similar to a trackball, replacing the wheel, with this you can scroll freely in any direction directly in the mouse.
