The trackpad is one place where Apple’s infamous one-button obsession actually works: no finger gymnastics are required for a right-click — you just put two fingers on the touchpad and press the single, big button with your thumb: perfect for both righties and southpaws.
Because there is no such software trickery when running OS X on the Wind, I bought a mouse, the Logitech VX Nano; a tiny, laser-toting wireless specimen which, despite its size, manages to pack most of Logitech’s full-sized gimmicks inside.
First, let’s compare the VX Nano to it’s new, younger brother, the v550 travel mouse. Both feature the same tiny USB dongle which slots into a USB port and stays there, like a hermit crab finding a new shell. Here are the differences, and the reasons I bought the older model.
V550
Clip and Go dock. This little nubbin sticks onto the case of your notebook and the mouse hooks on for portability. “Docking” also switches off the mouse, which saves a task. The regular Nano comes with a little padded pouch instead (pictured above), which is actually nore useful when you put the computer into a sleeve.
The V550 has a couple more things not found on the VX: the first is ambidextrosity. Because the design lacks side buttons, the sinister members of our species will be equally at home with it. The second is “Document Quick-Flip”, a software feature which pops up a document selector when you hit the right button.

The VX Nano is really just a smaller version of the desktop mice with a few buttons missing. The included Logitech software lets you assign the buttons to various functions, including keystrokes, so you can perform any function you like. The Mac has built-in support for multi-button mice, but it's worth installing the software just for the fancy scroll function.
The scroll wheel is weighted and spins freely (a hefty push will click it into a regular mode). This means you can scroll through long documents easily, and when you get to where you want to, you just put your finger on the wheel to stop it. It's also very useful with video software, allowing you to scrub through clips at high speed, stop, and then advance frame-by-frame.
The wheel also tilts: mine is assigned to click forward and back in browser windows. Two more buttons live on the left side, with another below the wheel. The left-side buttons would be better placed on the actual side under the thumb, but maybe I just have big hands.
Underneath is the laser-hole, four slippery PTFE feet (not found on the v550), and a power switch and light which, like a refrigerator light, only comes on when you're looking (I checked) and requires a long press to switch on and off. The laser, like those on other Logitech mice, tracks on almost anything, from glass to jeans.
You also see the button to release the bottom panel. This is actually fun to open, like the secret floor hatch in the original Millennium Falcon toy. Inside you'll find...
... the batteries (2x AAA, included) and the nubbin. The batteries, according to the Logitech software, will last me for another 164.7 days. Which brings us to the Nubbin, or the plug-and-forget Nano-receiver, as Logitech would have it. The nubbin is a tiny USB dongle which communicates with the mouse in the 2.4GHz range. It drops out a lot less than a Bluetooth mouse, and runs at full USB speed, which should make things more accurate. It certainly picks up the signal fast enough: there is zero delay between plugging in and being able to use the mouse.
The kit also comes with a desktop USB extender cable, although this doesn't contain a receiver -- it's just a fancy USB extender. Here's the Nubbin:
And because we often get complaints that you can't judge the size of things from photos, here it is again, with a piece of string for size comparison:
Just kidding. Here it is with a standard iPod USB cable:
It is indeed "plug and forget", unless you want to use the mouse with more than one computer.
The VX Nano is a great little mouse. If you don't need the portability, go with something a little bigger to avoid wrist strain. If you have a notebook with an awful trackpad, though, this will save both your tendons and your frustration. The Nubbin and the weighted scroll-wheel really make the mouse shine, and the two AAAs lend it enough weight to feel solid and accurate. Verdict: Success.
