MS software can seriously waste your weekend!
I totally trashed GDM (Gnome Display Manager - one of the many choices for a graphical desktop environment for *nix) the other day on my Ubuntu system (completely my own fault, being a little too zealous when removing 'orphaned' packages).
This in itself is not a unique Linux phenomena, I have terminally broken *plenty* of Win installations, they are just not as easy to fix.
So, I was faced with two simple choices (only no.2 would have been available with Windoze);
1) find, fix and reinstall the broken packages using the command line.
2) reinstall the OS.
I estimated that I might spend and hour or more on option 1, so I got out my CD and reinstalled (20mins).
Now, *here's the real killer*. After reinstalling the OS from scratch and rebooting, everything was still as I left it. Junk on my desktop, emails in my inbox, all passwords remembered, browser favourites, even my WPA keys! Do that on a windows box. I bet you can't.
Personally, I have pi$$ed away entire weekends reinstalling Windoze and the apps I had, then copying back all my data (if I had a recent backup).
The secret sauce? my home directory (it's like 'My Documents' but better because it actually contains *all* your stuff!) lives on a separate partition to the OS.
People that whine about Linux being hard to use make me want to puke. Have these people used Windows? I can only imaging that they haven't. My 2 year old daughter can use a Ubuntu machine with ease and, best of all, she can't break it. She can break a windows box in a few minutes!
