I have two monitors hooked up to a Matrox graphics card at work. Sometimes I feel like I couldn't live without the 2nd monitor, and sometimes I feel like I'm just causing myself neck pains (since the desk doesn't facilitate placing the monitors in any ergonomic way...). The latter point of view seems to be dominant nowadays.

Still, when I see something like this or this, I feel an unimaginable itch to run to the nearest geek heaven and make my credit card squeal like a pig...

...and then, of course, I remember the old 800MHz Linux box I have lying around un-plugged that I really should hook up, upgrade the OS, and spend any spare moments (including the hours when 99,5% of the local population is sound asleep) with tweaking the crontab and init files. It's got a 14" monitor. I can't believe I've actually coded with that thing not so many years ago.
