Model M fo' life
One of the unpublished advantages of the Model M is the lack of a Windows key. It frustrates the hell out of random scammer calls. "OK, so what key is next to the Ctrl key on your keyboard?" "Um, a blank spot?" "You LIE!"
This aside from the obvious advantages of:
1 - LOUD - You KNOW when I'm typing
2 - Durable - I have three - one at home, one at work, one spare. The spare is unlikely to ever be necessary
3 - Heavy - Not gonna shift around while I whack on it
4 - Removable keycaps can be run through the washing machine in a lingerie bag
5 - Durable - Did I say that? Only have to rinse the blood of the user off before writing the post contact report.
6 - BEST tactile response of any keyboard, ever. Of course, I learned to type on a manual typewriter, so there's that...
Plus already paid for and less than 200 quid each to begin with. WTF are they thinking?
