I'm on my 2011 laptop. Battery's pretty bad; I might get half an hour or something (last time I tested). Shortly after I bought it, I replaced the HDD with a hybrid HDD+SSD (500GB spinning, 16GB solid-state cache, or something). My kid bent something in the keyboard, so the F12 key sticks up a little bit. Everything else works like when I bought it.

I sometimes get the "new tech" itch, but I haven't convinced myself that I'd get enough benefit to retire this thing, yet.
