I think my Toshiba laptop is well out of the running --
-- it's original OS was early Vista.
Not an expensive computer, but over its lifespan it's run every 32-bit OS I put on it. Still chugging along, currently with Q4OS, PCLinux, Mint, and Salix in multi-boot. Whatever Toshiba's current rep, I bear much fondness for the dreadful plastic little beast they made in 2008.
