In today's world, there are so many options out there when it comes to computers and their wireless devices. What is important though is what type of mouse you should buy based on your needs. If you plan on spending a lot of time at a computer then you probably want to invest in a good wireless mouse with high DPI for easy tracking. On the other hand, if you just plan on using your computer for casual browsing or surfing the internet then you probably will not be concerned with the DPI. It is more important that the wireless mouse works well with your computer and its other accessories.
