I don't like linux as a desktop. I have had so many things that don't work properly on my machine that its not worth it. It is a slightly unusual machine being a convertible tablet with a multitouch screen.
You can buy 32 Gb sticks for about £17 inc P&P.
They run on old computers, you know the ones that use so much electricity they would pay for a new PC in a few months.
What expensive taxation?
There is no money in linux or other free software. People download it, decide they don't like it and buy office home and student, or get a copy off their friends (it can run on three machines so its only ~£20 a copy).
Its life.
