The trouble with many notebook mice is that they lack the same level of functionality as their desktop counterparts. When taking on a smaller form factor, these smaller mice tend to lose extra buttons and things that make full-sized mice so much nicer. Thankfully, this is not the case with the VX Nano. With the exception of the zoom slider, the VX Nano can do just about everything that the larger VX Revolution can do. it's almost up there with the MX, despite being about half the size.
