In reply to TobyA:
I have Lubuntu on two machines - my Asus eee which I take away for basic word processing function and browsing, and my wife's laptop for similar tasks.
I'm not a tech dunce but neither am I an expert. My main source for answers are Google and the Linux forums. There is in my experience nothing about Linux that can't be answered somewhere, so the shroud of mystery surrounding Linux shouldn't be a block to trying it.
There is now lots of software that nearly perfectly matches anything by the big guns: Open Office (Libre Office) for Office suites, all the web browsers are available and work exactly as if on Windows machines (Firefox, Opera etc), video playback software etc.
My wife is a complete dunce when around computers but all I've done is try to get the desktop to look and act in a similar fashion to the Windows environment she was familiar with - so basically everything is iconified on the desktop and she just clicks on it.
The reason for going Linux was to take advantage of their small footprint when it comes to running on very basic machines. I've never had any hardware conflicts or issues while using Lubuntu and anything I've plugged in (e.g. wifi adapters) has worked. My wife's Nokia/Windows phone hooks up straight away to the laptop for easy transfer of files.
I have some mapping software (Anquet) which is proving difficult to get to work with Linux (it's not natively supported) and this is the only reason I still have Windows on my main PC (though I do have a Lubuntu partition).
As for games, not really a player of them on PC (I do have an old PS2 for that) but apparently there are very few.
