I think its always dangerous to make overarching statements that are meant encompass a whole category of applications. (this goes for multi-column keys too..)

I have found myself many times with my laptop in my car but unable to check my work's webmail to double check my calender because I'm offline.

Just to expand a bit I think its necessary for anyone building a webapp to look at how and why people need to access their app and develop accordingly.
