The Logitech Anywhere MX mouse is the successor to the VX Nano mouse.  This new mouse boasts Darkfield technology and utilizes the Unifying receiver.  It is contoured to better fit your hand and place the forward and back buttons in a place that is easy to reach with your thumb. The tracking system is laser based for a high degree of accuracy and precision.

With the Anywhere mouse, I found it quite easy to navigate my two 1600 x 1050 screens quickly and without error. The motion of the mouse is nice and smooth and a pleasure to use. Its contours helped my hand and wrist reach a natural position. This is unusual for a laptop style mouse. The forward and back buttons are also a nice feature that laptop mice generally go without.

The new Unifying Receiver is way overdue in my opinion.  This new technology lets you connect up to 6 compatible devices using just the one receiver.  This is exciting, but not as wonderful as the actual size of the receiver. It is very small and hard to notice when plugged into the computer. My previous mouse had a long receiver that stuck way out and was a pain to maneuver around with. Since the Unifying Receiver is so small you can leave it plugged in when storing your laptop in a case or plugging in other USB devices. If you do unplug it, there is a handy compartment inside the battery storage underneath to plug it in.

The mouse uses two AA batteries so it is a little on the heavy side.  Other reviewers online wrote this off as a downside to this mouse. Personally, I like the extra weight while using it. The mouse will also work with only one of the batteries. So, if you like your mouse lighter, it will accommodate you.  I prefer the use of AA or AAA batteries in my electronics these days.  They allow me to buy generic NiMH batteries that I can charge and use across all my devices. The large on/off switch on the bottom is very nice and makes it easier to conserve battery life.

I could do without the Hyperscroll feature on the scroll wheel. It is nice to be able to scroll very quickly through a large document but in smaller ones it is a little over kill.  I noticed a weird quirk where the wheel seemed to be stuck between 2 clicks and keeps scrolling my document even though I am not actively scrolling it.

There is a button behind the scroll wheel that lets you switch between programs easier, in theory. The program switching button left me confused and befuddled at first.  I accidently hit my mouse on the couch I was sitting on and as far as I could tell, my computer started freaking out.  I have used it a couple of times since then, and it is nice, but not something I will be using much.

The cost is a little steep for a mobile computing accessory.  A similar Microsoft mouse is about half the price.  The Microsoft mouse does not seem to be as ergonomic or have as nice of a shape however.  As far as extras go, this mouse is well equipped.  It comes with 2 Duracell AA batteries, not some no-name brand that you often get with electronics.  As an added bonus, it comes with a faux-leather protective carrying case which I thought was pretty classy.

Over all, I am very pleased with this mouse.  I just upgraded from an older V220 because my new laptop has a much higher resolution.  I am glad I did, the older mouse was having issues travelling across the screen and I was becoming impatient with it.  I enjoy the action of the mouse and the feel of the material it was constructed with.  Since it is a little on the pricey side, and the scroll wheel is not perfect, I cannot give it a perfect score.  It’s Geektime gives the Logitech Anywhere MX mouse a solid 9 on the d10 of mobile computing.
