Microsoft’s most portable wireless notebook mouse is The model 5000. It
connects directly to a bluetooth PC without a transceiver & also freeing up
USB ports for other devices. Microsoft calls it a “high definition” laser
mouse which they say makes it more precise and responsive, and that it
delivers smoother tracking. The 5000 has an ambidextrous design which means
you can use it with either your left or right hand and it is comfortable
both ways. It also has a bit of an ergonomic design so it will help reduce
discomfort during long hours of work and will help prevent some serious
long-term conditions. It has four buttons including a Back button and the
scroll wheel. You can use the Back button to easily navigate between
folders and web pages, or you can press the scroll wheel to enable
auto-scroll. Auto-scroll saves time and effort since you can navigate
documents and websites without using the on-screen scroll bar. This mouse
also claims a 3+ month battery life which can be achieved by turning the
device off when not in use. When it finally does get close to running out
of power it has a red LED indicator light that illuminates to alert you
when the battery is almost dead. This mouse is a mix of light gray, dark
gray and black in color and the MSRP is $49.99.
