Well I can't say I have given this a lot of thought lately but yes there are
definite advantages and productivity gains to be had by using applications
that can work the way you need when disconnected. As such a certain
percentage of new software will be written to take advantage of that. That
does not mean everything will change but many professions are already
demanding remote or offline access today.
