Does not reflect my experience at all. T420 from 2011 is still completely usable. Haven't clocked the boot-up time but definitely not minutes, more like a couple dozen seconds. Everything worked out of box with latest stable Debian. Can do 2560x1600 over the DP connector, too. This is not even a top-spec model but the slowest i5 available back then.

To be fair, they didn't say /what/ computer from 2011 ran terribly. The Intel Core CPU's were the best back then. There were also Atom netbooks, terrible AMD chips, etc. AMD solidly has the performance crown now, but in 2011 they did not.

Pretty much anything from 2011 that was not a Core i5 or better will probably not run well today unless you use a purpose-built ultralight distro.
