Again, I keep repeating: I'm a power user. I'm a software developer and do a lot of web development; I need several browsers on my PC, including various plugins, to do my work. If Linux wasn't adequate, I would be the first to discover it, not the last.
Imagine a hammer that is used by a handyman to do 25 different things, all day every day. Then I come along and ask, "Yes, but will it drive a nail into the wall? That's what I need done..." Um, DUH! of course it will! If it will do various exotic tasks for that handyman (a specialist), things you'll never need to do, of course it can do the absolute basics like driving a nail in the wall.
