Fonts look like shit? They've looked fine in my past experiences. After video card drivers were installed, of course. I'm going to hope you did that.
Anyhow, install a fresh version of windows. (Not the manufacturer's restore disks but a bare naked install like you did with Linux.) In comparison, 'nix is a walk in the park.
Fonts are subjective, and to some extent dependant on your screen type
just pick one you like
PPPoE should be handled by a router (via it's web interface) not your OS
it sounds like you're doing it wrong
you *can* set your machine up to act as a router / firewall to other machines
but for a home setup with modest need for fine control, I wouldn't advise it
plus your machine will need to be on 24/7.
use a router, that's what they're designed for.
mouse wheel scrolling is *sort of* a known issue in gnome
there's no way to say "one wheel scroll = move 3 lines of text" like you can in Windows
you can do this in KDE, but not gnome
now, rightly or wrongly, it's not considered important to the gnome people
But consider who you're looking at
developers who spend a large amount of time looking at multiple, often large, text files at the same time and need to flick about the page.
and they don't think it's that important
The scroll wheel is good for quick flicking around a small area of text
but for reading a page top to bottom, it's not that good
use page-up & page-down, again, it's what they're designed for
TBH the best thing in Ubuntu is the FreeSans font. Makes the web look lully.
