But I'd say most people who keep up with software development believe that's the case. <rant>I think that would be pretty bad if the best we'll ever be able to do is Javascript.</rant> Anyway, IF most apps people are using are Web based and compatible with Firefox or a Flash version supported in Ubuntu ... it seems less and less like there would be much point in paying for, using, and dealing with Windows.

I think most seniors can just about already switch fine to Ubuntu.

Or Java.

Applets - they don't suck as badly anymore!
