I was just reading this article and I just remembered going through the same last week as I cleaned out a windoz box for a friend. Rebooting like 20 times after an update of this or that, and that’s on new hardware. I could not even compare the experience to when I do installs on my Linux test box, most installs are done in less than thirty minutes and you are up and running. Installing Linux is such a breeze I don’t even have to think that much about it, while for windoz i have to plan for it and make sure I have enough time to just sit there and watch precious time being wasted.
I had to install the base OS and each service pack separately and restart some more, now on linux you might have to reboot only if there is an upgrade to the kernel, but generally updates don’t require a reboot.
