I think a lot of people are just slaves to consumerism. Here's my story:
My wifes mother wanted access to this 'Facebook' that everybody's talking about. However, she didn't have a phone line and didn't want to be tied to ANY contract or anything of course she didn't want to have to payout loads of cash either. So, I put together a PC for her from bits I had lying around, a very decent Pc as it happened: P4 1.8Gighz, 1Gig ram, Nvidia Gforce4 graphics. I installed Ubuntu with the netbook remix interface (she had never used a PC of ANY kind before but had used a mobile phone). I also bought her a 3 Mobile broadband Pay As You Go dongle. Set it all up, away she went.
A week goes by, she checks facebook, find recipes on google etc. Great, I think, a job well done and another linux user (who doesn't even know it). Great, until she announces that she's buying a laptop because "the computer is too bulky" (meaning the CRT and base unit is too big - even though she has a huge room and even bought a new desk to accomodate the PC!).
So, there you go, even though I had provided her with a perfectly working PC the lure of consumerism was too much and the 'need' to spend some money will create another Windows user!
Well, I'm not doing windows technical support so she can forget that...
