Ok, so, I have been around windows pretty much my whole life and when I went to school, I used mac....eh. Anyway, I've heard of linux about 3 years ago, but never really messed around with it or seen what it looks like till about 8 months ago. I asked for a free Ubuntu live boot, and have never known anything to be so GUIlisious. It's pretty much my main OS now, especially since my windows partition got a severe "cold" last week and had to do a redo. Oh well, I had upgraded my HDD to a 200gb so I still had a majority of my data before it go pneumonia. By the way, it's my notebook that's dual-boot. I have disks for OpenSuse 11 KDE and Gnome, Fedora 9, gOS Rocket, Mandriva, CentOS Enterprise, and D.S.L. (pointless but neat...can be installed on a 64mb flash drive), but I like Ubuntu the most considering it was the one I "dove" into first. The only thing I didn't like is it took about a week to find the DVD playback codec/library. It's all good now.
And yes I do recommend Linux to anyone who is willing to try something new. Who knows, you might like and it might even like you back.
