Think of it as a toaster.
(OK, it can't roast CD's but...)
It's a personal machine. I don't need multiple users, nor an administrator account. Bit like a pocket calculator I can loan my mate. I really don't need security on my eeepc, as for my calculator - anyone can borrow it - and often do at school. My documents, etc, hide in "Google Cloud". I just whip it out (ooer, missus) when I need it.
Yep OK, I'll 'fess up - I put eeebuntu on the asus701, but it ain't my main machine. Currently, the only pages it goes to are sanakirja.org (for school use), www.mol.fi (for a job), www.linjakas.fi (for the bus), news sites and my gmail account. Oh, and the bank, for paying bills when I'm on my lunchbreak. But, the latter's seriously protected by their one-time password and (memorised) 8-digit customer number.
Does the trick. I wish they hadn't 'died the death' they seem to have. Damn useful thing to have in my 'man-bag'.
