On desktops

In the recent craze over smartphones, tablets, and what I'll term webbooks (think ChromeOS machines), many companies seem to have forgotten the greatest achievement of modern desktop operating systems, namely the ability to multitask. Smartphone OSes originally either did not have this capability built in or did not expose it to the end user. This was understandable, as smartphones operate under different constraints with respect to power and screen space. Even tablets, with their higher power envelopes and bigger screens, are ultimately presented as consumption devices.
