Re: Going on-site has certainly been made redundant in IT
Its really hard to install a new server in a data center in downtown Atlanta, from my sun room 20 miles away. Also, 'remote hands' or whatever your DC provider calls dicking with your equipment, costs have risen over the last year. So, while software developers who have, since before 1975, been capable of working from home*, hardware installations still require someone on-site...but not very often at all.
* - the computer probably costs about half the price of your family car once you added a crt, modem, printer, and....connection charges, but if you didn't need to commute, you didn't need a car.
edit: complete sentence...
