I've recently looked at Ubuntu's 10.04 and 10.10 installers, and they are quite nifty tools, so fresh and gorgeous, and so easy to use that nobody would dare say "I can't install Linux!". And then I recently re-installed my Debian system and I don't really see how much harder it is to use than Ubuntu's (except that it's far uglier, so I guess that also makes it intimidating).
What triggered this post is the following titbit:
d-i [Debian Installer] is the very first thing many of our users see, and has a huge range of uses, from simple desktop installs to massive corporate deployments; it's unspeakably important that it works well, and it's a testament to its design that it's been able to trundle along without actually very much serious refactoring for the best part of five years now.
In addition, this tool (or rather, a set of tools) also happens to be rock-solid tool, and its great reliability gets admiration from me on each install (and I've done dozens, with not one instance of data loss).
