Ubuntu has been touted as one of the easiest linux distributions to use. Yuga points out that it failed Serdar Yegulalp's "Granny test" in an article over at Information Week pitting it against Windows Vista.
I hate to say it but I also fell for the "easiest linux" hype. I've been a linux user for 6 years and it's never been as "easy" as Windows.
When I plugin my digital camera to a Windows machine I'm almost certain that it'll just work and that it will show me my photos in an automatically created drive in windows explorer.
In much the same way, I am almost certain that when I plugin the same device to my SuSE Linux machine, I'm bound to check the logs or manually type in a mount command. Apparently it's the same for Ubuntu too.
I recently installed Ubuntu 7 on my brother's PC (who has been using windows since he started using a computer) and he has nothing but complaints. They're nothing a little tweaking can't fix but still cumbersome to not have been preset or configured out of the box.
In conclusion, I agree that Ubuntu has some ways to go. It's probably the easiest linux distribution but it still not as easy as Windows in some cases.
