I come to this place often to get answers usually without logging in apparently
But I've used Linux in one form or another for around 9 years. At work I use Fedora Core and for my personal use I use Ubuntu and also Fedora Core since it's what I use at work.
I run Linux everywhere possible and will always take it and fight for it over the Windows mentality that pervades everywhere.
It's on my laptop, my Ultra Portable, and a couple of my desktops.
At work we use it as a base for a customized product.
Cheers,
