> But I've never delayed upgrading, and I've never regretted it.

I was the same way for until one of the upgrades, I forget which, broke resume from suspend about 10-20% of the time for my combination of laptop and monitor. Every morning I’d get a sense of dread when I tried to open the laptop to see if today was a day where I’d get to pick up where I left off or if I was in for a crash and reboot as soon as I tried to use the laptop.

I thought for sure it would be fixed with one of the point updates, but it went on for the better part of a year.
