72% of the South African workforce is not working at home...
The vitual workforce was also not created thanks to Apple or any of their largely insignificant gadgets in this regard. Instead, support for mobile working has come from the advent of unified communications and presence. E.g. Softphone applications that run on your computer at home, that log you into your extension at work, so people can call you and have absolutely no idea that you aren't in the office. This sort of functionality was available on Symbian phones before Facebook was released, for some context. Presence related services, like your MSN messenger for example, or gtalk, further fascilitate virtual working and are used extensively in large, modern, corporates around the world that need a simplistic way of instantly communicating with people across timezones and borders.
