> Just upgraded my Ubuntu, too
I updated a bunch of Debian installs - both virtual as well as bare metal - not that long ago. The updates took a few minutes for the download (around a gigabyte, that is for the OS and the installed application software) and maybe 10-15 minutes for the actual upgrade, depending on the platform and the number of installed packages. After that, things... just worked. Strange, this, how those ballyhooed commercial it-just-works Rube Goldberg devices need tens of gigabytes and multiple update attempts to get a basic operating system update which removes features and increases the vendor's stranglehold while you can just install something like Debian and have something which works for far less money in far less time with far fewer hassles and far more freedom. Oh well, to each his own I guess, I'll just continue doing what I've been doing since '93, having seen the Windows world go from Windows 3.x through 95, 98, ME, NT 3.1, NT 3.5, NT4.x, 2000, XP, Vista, 7, 8 and now 10 and the Apple world from Mac OS 7.x through 8.x, 9.x, X.lots-of-animals, X.lots-of-places, not to mention 3 and soon 4 CPU architectures - not that those had that much of an impact by the way.
Meanwhile I can still use scripts I wrote back in the day. Running binaries from that time is a no-go unless I install one of those older distributions in a VM. Still, time spent learning "Linux" was and is time well spent compared to time spent learning one of those commercial systems. Linux just... keeps better. Lasts longer. Linux is like a cockroach, when all apples have rotten and all windows been smashed there will be some Linux overlooking the rubble of those once mighty empires.
So, have fun, all you apple pickers, you windows cleaners, and know there is always a way out when the apples get too sour, the windows too opaque.
