Hardware just chuggs along ...
My main desktop is a 7 y/old AMD Bulldozer, 32 GB RAM. I have had to replace some fans, the PSU & a disk but that is about it; oh - I upgraded the screen a while back. I run Linux so upgrade problems are not an issue. It is still plenty fast enough. I expect to continue to run this for a few more years.
Laptop: a small HP Stream. Not a heavy CPU which means the battery lasts. Cheap: so that when I drop it under a bus I won't cry (much).
