Failing that, can anyone suggest a good place to buy a good Linux laptop? I'm about halfway between King's Lynn and Cambridge, so on the King's Lynn/Downham Market/Littleport/Ely/Cambridge axis. I'd prefer tp avoid having to go into Norwich -- or even Cambridge! [access to shops not easy].
What's the budget and how big do you want?
Lenovo Thinkpad T series (14") and X series (12") are excellent for Linux and you can buy refurbished ones at very reasonable prices from such as Tier1 and Morgans.
