The laptop I'm using now, and have been using for a bit over a year now is --not sure of the exact vintage but-- pre-2004. It is my every day machine at home.

The laptop I'm using now, and have been using for a bit over a year now is --not sure of the exact vintage but-- pre-2004. It is my every day machine at home. Now I haven't actually upgraded it in that time, so it's not really a data point against unserviceable machines but it's sure as hell a data point against 2 year life spans.
