when i had only one M122 i did carry it to and from work, only on the weekend though, the only issue is how heavy the thing is, now that i have fixed another one i do not need to do so, i yeah someone could steal it, but it being PS/2 and next to a much easier to steal laptop i guess that if someone were to steal something it would not be that old looking thing.
You carry an M122 to and from work? Wow. That's dedication. I would just buy another M122, or better yet, an F122. I was surprised to see BrooklynTony198 say they carry a regular M around.
If you don't use the top case shell, you can put a carrying handle on your Model F 122-key.
That is a thing of beauty.
I leave an F AT at the middle school and a DC-2014 at the high school. I'm rarely at other buildings in the district, and rarely ever need my work laptop (even though the middle school desktop has a core 2 duo in it), so I have no real need to carry a keyboard around with me. I did get an Ajazz AK33 75% for that purpose, for the few cases I may actually use my laptop (which I now just leave at home most of the time anyway) but the switches are the worst Cherry clones I have ever had the displeasure of trying and the rgb leds are, bizarrely, mounted above the switches ... so swapping in jades or navies would be a pain. I have a TG3 BL82 I modded jades into, but those bricks are thick ... and heavy, and have no Windows key, which I use constantly at work (the desktops have usb foot pedals mapped to the windows key). Otherwise I would think about carrying that for the few times I do use my laptop.
