The point of a higher resolution is usually greater visual clarity, not
seeing more on the screen. Having things at a higher resolution means the
edges of fonts are less jagged, and things are usually clearer. Most of the
users I've come across who go to a higher resolution don't like the fact
that things are smaller, because they're also harder to see, and want it
large again. Programmers, on the other hand, and technophiles in general,
like it smaller so they can get more stuff on the screen.
But again, as per my other post, in my situation, it's not going to a higher
resolution (and things getting smaller) that's the issue, but going to a
lower resolution (and things getting bigger) that's the issue.
