Wasn't this problem solved by docking stations? Take the computer with you when you want, leave it plugged into the desk when you don't? Seems like there isn't a need for this type of machine.

I don't want an employer provided machine. It's one more thing of theirs I need to take care of. Never mind that some employers go bonkers when you use a "work" machine for non work purposes.

Combine this with the fact that most work machines are simply ancient, and loaded with all sorts of crap then I have even less desire to use theirs.

Just give me a copy of the VPN software and ill take care of myself.
