Debian Installer Beta 3 Usability Review
Marcus Thiesen writes "Debian Installer Beta 3 was released two days ago and I wrote a small review concerning the installation part. The new debian installer is good way to set up your favorite distribution. Nontheless there are a few usability things and I thought that it might be a good idea to write a walkthrough from another point of view: Bob 'average' User."
You most likely used the Network Install from Debian 3.0 (boot-floppies) which is 2 years old. The current installer is available from http://www.debian.org/devel/debian-installer/ for testing and fixes most of the problems you mentioned with respect to autodetection, etc. It has worked well for me for the past year.
