Linux is still nowhere near the point where a non-techie will consider adopting it.
Not necessarily, Linux isn't anywhere near Windoze, let alone Mac - but it has come leaps and bounds in the last decade. I've just finished installing Kubuntu and KDE4.1 for friends of my parents - they are in their 60's ~ 70's and know ZERO about technology.
The whole thing started out with him asking me to take a look at his desktop because he couldn't enable the automatic updates - looked/acted as if TrendMicro disabled that option for security or something for some reason. After a few beers, and BS'ing about things - we got to talking about Firefox, Thunderbird and Linux (FOSS). He started getting all gitty about things when I explained that Linux is mostly immune to viruses - I've been using it solely for a couple of decades now and have never had a virus problem, and routinely hit up sites that are known for malware and just chuckle when they try to run. I explained to him that if by some chance I did come across one made for Linux, all I would have to do is create a new user simply because of the basic security on a *NIX system - the core system will never get infected like it does under Windows with the typical user having administrator rights.
He asked if we could get together after the 1st, and I said of course. I pretty much blew it off, thinking it was the beer talking - but earlier this week he called asking if I could come over and look at his system. It had become infected with some kind of virus that Trend could do nothing about, it would just pull up a window saying it can't do anything about it, you close it and it comes back up with in a few minutes. I had brought over the Kubuntu install disk with me and showed him KDE, OpenOffice, Firefox, Thunderbird and Adept where he can search for practically any kind of software and simply hit install - it's all free...
I ended up resizing the partitions and installing Kubuntu on both his desktop and laptops, both had infections that Trend either missed or couldn't do anything about. The desktop was twice as fast as the laptop but with half the RAM (512mb), it was dog slow under windows (6+ hrs to zip 200 1mb images that took Linux less than a minute - he just laughed when he saw that). Linux ran the desktop just fine, even with only 512MB, the CD burner even started working again (the burning part). And when I got the laptop to see the desktop through CIFS and over wireless (which wasn't working either under Windows), he was 100% sold on Linux and told his wife they are going to get another 1G of RAM for the desktop and a new printer since the DELL was a "paperweight" according to linuxprinting.org, which he got a kick out of - the communities since of humor, like the kernel reporting "OOPS" when it hits a bug.
I was surprised to see that WINE had installed and ran his PokerStars application with out any issues what so ever (www.pokerstars.com). I kept telling them that they could boot back into windows at anytime they got tired or frustrated with Linux - and he just nodded and said that Windows was a pile of crap and never wanted to use it again. All he cared about was his PokerStars (WINE), WORD docs (OpenOffice), surfing the web (FireFox) and Email (Thunderbird) - after walking him and his wife through everything, they were 100% sold. His wife made the comment that it looks exactly the same, just a little different in how to do things...
Point being, that Linux has come 1000 miles in a short time - and as long as the given person *knows* what is up and what to expect, they will fall in love too with the hansom penguin:-)
