Logitech MX Anywhere Mouse with Linux (Review)

From: andrew cooke <andrew@...>

Date: Sat, 16 Jan 2010 14:38:35 -0300

So, one of the other gadgets I bought while in the States was a
Logitech MX Anywhere Mouse.  It's pretty nice - has a nice weight
(thanks to the two AA batteries it needs), looks fine (would be better
with a little less shiny metallic trim, but OK anyway) and is a nice
size.  And it works out of the box on Linux - you just plug a tiny
little dongle into the machine's USB port which receives the wireless
data.

However there is one annoyance - the middle click is a separate
button, behind the scroll wheel.  That takes some getting used to,
because you need to bend you finger quite a bit to reach it.  Also, it
has two extra buttons on the left side that don't make much sense if
you're left handed (I am a left-handed mouser).

On the other hand (and the main reason I bought it), it works just
fine on glass.  At first I thought it was having problems, but it
turned out that the receiver dongle thing has limited range - I
originally plugged it in a USB port on the back of my "desktop"
(actually quite a large box under my desk); it works much better from
a port on the front.

One curious feature is that clicking the scroll wheel switches it from
"clicking" to "spinning freely".  Scrolling web pages with the
"spinning freely" setting is kinda fun...

Battery Life

From: andrew cooke <andrew@...>

So the original (Duracell AA) batteries lasted until today.  That's a little
over two months continual use (my work machine, used every day).
