As a counter-anecdote:
I'm typing this on a 7 or 8 year old s76 Gazelle. It was my primary work and personal machine for 3 or 4 years and has been my primary personal machine since. I did replace the original drive with an SSD, and I think I may need to replace the fans---they're getting loud. Hardware- and build-quality-wise, I've never had any problems. (Well, ok, I killed one of the USB ports. Probably broke some of the connections.)
The one problem I have had is with the NVidia graphics, which have never worked properly. (I've got graphics acceleration disabled now.) Either it wouldn't go to sleep, or the graphics wouldn't wake up. The last straw was when I got those problems beaten into a standstill, and Chrome started somehow overriding my window manager and keeping the (accelerated) Chrome window front and center, minus WM decorations.
Sure, it's a generic Clio or something, but I've been very impressed. Never had much love for HP, though.
