Okay, you dont learn
Linux, you get into it
, it kinda grows on you. That said, Ubuntu is a winner, even if it seems overkill.
Ubuntu is an easy distro, but, if you'd feel inclided to try an alternative, Macpup
, or Puppy
are great little lite-w8 distros...
Be aware, though, that it requires a reinstall that will ultimately make you end up where you are now: using a browser to surf and a mailreader to read the mails.
Werther Ubuntu, MacPup, Fedora, Arch or any other distro, you'll find Firefox on any of them, or Evolution.
The choice in your case may not really be the distro, but the software on that distro
Personally, I'd stick with Ubuntu. It's a helpfull all-rounder. Maybe, though, an alternative set of software tools for your purpose could be called for, dunnow...
And, by the way bien venido aqui
