I know there have already been a bunch of "my parents use Linux" posts, but I thought I'd add another, in case there's someone who's /almost/ convinced.
My mother had a laptop struggling under XP. It would take an eternity to boot, and there was lag even when typing. I installed Ubuntu 12.04 for her, and she loves it. She uses the browser, LibreOffice and one of those photo-viewing apps. Zero problems.
My friend's mother has been on Ubuntu for ages, too. She's happy and won't even look at a Windows machine, now.
I myself have only been using Ubuntu on my laptop for a year. I had zero hardware problems with installing 12.04 on my cheap, plastic-hinged, bendy Sony Vaio. I use a dual-screen setup, too.
Maybe the author should give Linux a try again. The OS (especially Ubuntu) has come a long way, in terms of drivers and usability. I had tried Linux on a cheap laptop around 6 years ago and given up. Totally different now.
