Your last point is really interesting.

I use a desktop at home and a small laptop on the go, and everything I need is always on both computers. Files, bookmarks, browsing history, you name it. I can just log into either computer and keep working. The advent of cloud-based synchronization tools makes it very easy for people to juggle 2 or more computers. So instead of fighting over the "Desktop of laptop?" question, one can get both and not suffer any inconvenience.

After all, what would the average North American middle-class family do if they needed a vehicle that was both large enough for the kids' hockey games and fuel-efficient enough for the dad's long commute? They wouldn't settle for one mid-sized car; they'd buy a minivan and a Prius.

The proportion of people who are "always on the go" is rather small.
