Did you tell your friend about PackageKit or Smart and the all the distros they both work on? I've used "Apt4RPM" on multiple distros, it works great. What about ZeroInstall and all its clones that let you build "install anywhere" linux packages by bundling libraries? Or gnome-app-install (Add/Remove Programs) or MintInstall or Appnr or even Click'n'Run that all provide user-friendly installation of software in less clicks than Windows?
Or that any package manager in any major distro allows searching of indexed metadata so you can look for "mp3 player" instead of "Amarok" or that every major distro already has packages for just about every stable, useful piece of software that will run on Linux and that the whole "we can't build universal packages" meme is an excuse from short-sighted programmers who don't want to provide distros with copies of their code to package.
Fine, whatever, their code, their choice, but don't lay it on the Linux community, if you give them a copy of useful, stable code they'll package it. Pore through the package repositories of any older distro -- Suse, Fedora, Debian, Mandriva, Slackware. You'll find programs packaged that probably 20 people in the whole world use. All at your fingertips just because the code was there and someone wanted to use it.
Your point about new terminology is just ridiculous. "Website?" "Blog?" "Download?" I guess I can't start using the internet because it has new terms for me to learn. The Internet is the largest, fastest-growing sector of ...
