I used to use a lot of Linuxes in my day, starting with Slackware in its late-90s heyday, some Red Hat and SuSE, a long period of Gentoo, and a whole mess of small distros I dabbled in (Libranet! Xandros! MEPIS! Fedora Core! Mandrake! The BSDs! Other crap I can't remember!)
And then, with the official release of Warty (4.10), I settled on Ubuntu. (And Debian for my servers).
Ubuntu's been quite good to me, but it's not nearly as customization-friendly as Gentoo was, and I miss the "start from a simple base system and build it up to what you want" approach. But I don't miss building EVERYTHING from source, or the portage breakage I experienced in my last days of using Gentoo.
That's what makes Arch look interesting. Parallel "install from binary" and "build from source" package trees, a pragmatic approach to non-free software versus a highly ideological one (I'm glad there are the Debians out there beating the drum for all-free software, but I prefer to stand on the middle ground myself), minimalistic, BSD-style init, the user-contributed community repository, etc. On paper at least, it looks like a good time.
I've been on Ubuntu for my desktop usage for so long, I don't know how much of what I've come to expect on my desktop is present upstream, and how much is patched in by Ubuntu. Ubuntu will stay on my work machine for the time being, but my home desktop could use a Linux to tinker with.
So, anyone have any Arch experiences they can share?
