I don't disagree, it's just a hassle (for me) that the trend seems to be towards Ubuntu for the desktop side of things. Fedora is still pretty popular, but the top three distros these days are all deb-based. This is mostly annoying when trying to google problems because it means I have to translate from ubuntu dependencies to Fedora to RHEL. If I had two weeks to just tear things down and get them back up and running, I'd probably just consider doing the whole migration to Ubuntu, but I don't have any particular need atm so it's not going to get done.
I agree about the consolidation and usability. The first distro I personally ever installed was a SuSELinux 9.0 (back before it was openSUSE). which worked okay, but I went back to Windows because at the time I was simply more familiar. I think that Ubuntu has done a good job of making the Linux user experience desirable and the work that their parent company is doing with mobile technologies is pushing them forward still. I think the Ubuntu Edge
idea is awesome, and would like to back it, but have not pulled the trigger yet.
