Good advice.
I suppose there's also a risk involved in following instructions that you find online at all if you don't really know what you're doing - either the risk is very small or I've been lucky. I think it's reasonably safe to assume that bad or malicious advice posted to the official Ubuntu forums would be shot down pretty quickly.

Running it directly from a USB stick is a good way to try it out to see if you like it before installing, but I think it slows things down considerably so you'd probably want to install it properly if you decide you like it.

One thing that I simply cannot get Linux to do for me is upload data from my Garmin watch - I just have to boot Windows (and use "Garmin Express") for that. If anyone knows a way round that I'd be glad to hear about it.
I also occasionally use an ancient DOS program for programming some (equally ancient) walkie-talkies that I use for work - Linux runs the program ok (using WINE) on the old laptop that I use for that, but I can't for the life of me get it to talk the serial port correctly so again I have to boot into Windows.
