Right after SuSE 10 came out last year I needed to install it on 5 computers for my robotics club. They were all old computers with no DVD drive, and at that point I was paying for my bandwidth by the GB, and thus I decided to go ahead and download all [SIZE="3"]6[/SIZE] SuSE CDs. Some ungodly number of hours later I had my .isos, which I then got the joy of burning.
At that point I had litterally no experience with Linux, and I actually found the SuSE installer very easy to use. It detected all the hardware in all five machines just fine. The single thing that made the whole install process just miserable and tedious was the fact that they didn't seem to have given any thought at all as to which packages should go onto which CD. Every single installation (each was a little different depending on what we intended to use the computer for) required the use of all 6 CDs. And rather than just go 1,2,3 etc they go 1,3,2,6,3 again,5,1 again or whatever. It drove me absolutely nuts.
Overall I liked what I was seeing of SuSE at school though, so I decided to go ahead and install it at home too. The computers at school I had just let go with the "nv" video driver, but at home I wanted to try to run America's Army (which at that point had a current linux release), so I needed the nvidia driver. But my video card was so old that the installer just plain didn't work, and I ended up building all these kernel modules and whatnot by hand.
BAD IDEA. It turned out that every week or so SuSE's (rather well done) automated update system would go back and undo all of my work at which point X wouldn't start. The first time it happened I had to totally reinstall since I had no idea what I was doing. Later I learned how to go in fix it (rebuild the kernel modules again, modify xorg.conf, etc) from the command line.
The need to rebuild the kernel module every week just to keep the GUI working drove me back to windows after about a month.
The only complaint I had with the SuSE installer was the ridiculous CD switching nonsense. And it did ask me whether I wanted KDE or Gnome.
