* Print out documents with my Epson printer. I didn't even have to use the driver disk to install this printer! Fedora Core already had the driver as part of the Fedora Core package.
* Internet browsing with Firefox and many other browsers (Epiphany, Galeon, Seamonkey, Konqueror, etc). With a combination of Firefox, Tor, a Firefox extension called Torbutton and Privoxy you can even do it anonymously!
* Email with Thunderbird. I was already using it in Windows and it seems to work even better in Linux! It has a built in spam filter which I learned to tweak to filter 80% of the spam I have been receiving.
* Encryption with GPG. This is an open source version of PGP and just as good if not better than PGP. Thunderbird has a plugin called Enigmail that uses GPG. I used to use a GUI for GPG called Kgpg, but found a better one called Seahorse.
* Create and mount encrypted volumes with Cryptsetup. It's similar in principle to PGP Disk.
* Type email and other documents in Japanese though in a non-Japanese language environment. (Yes, WIndows can do that too.)
* Setup different user accounts with their own individual language interfaces for different users. Windows can't do that as far as I know.
* Word processing with OpenOffice. I was already using OpenOffice for word processing and spreadsheet in Windows, and so was already familiar with it. OpenOffice, unlike MS Office, has a PDF exporter option
