Ok do you want to try an little experiment? Let’s say you install the latest version of Ubuntu. And 1 year later they have had two upgrades.
How do you upgrade? How much time does that take? Oh and you’re using a brand new laptop with a docking station with 3 monitors and RAID SSD built into the laptop.
Open a terminal and type:
sudo apt-get upgrade
Reboot when it tells you it’s done. Problem solved.
Ubuntu, specifically has LTS (Long Term Support) versions that will be patched regularly for a few years as part of their efforts to provide stable OS platforms. I’ve been using 12.04 for a year and I love it. I’m moving to 13.10 on some of my servers, but 12.04 is stable and safe.
