I have a feeling this thread might be moved, due to it turning to a discussion/I hate Microsoft-thread.
But Comcast and Microsoft are wrong. Internet Explorer is the most used web-browser out there, but why? It comes pre-installed on almost all computers sold. I am not sure of the exact numbers, but I seem to recall reading somewhere that 96+ % of all computers sold today incorporate Microsoft OS and software.
Even if it is a OS/software package easy to learn, it is not the best. I like Bill Gates personally. Who wouldn't? Starting a multi-billion dollar, global business in your garage/in a motel room? Not many have succeded in that.

For anyone who isn't afraid of trying new things on their computer, I refer you to Ubuntu, a derivative of the Debian/Linux project, guaranteed to release a new package every six months and give support for 18 months generally, and with 6.06 they give support for three years on desktops and five on servers. Only reason I am still using Microsoft is that I haven't gotten a new computer yet. When that day comes, I will backup what I need off this and use it as a learning ground for Ubuntu. I know I will use some time to get acquainted with it, and I don't want to loose my connection with this forum or my e-mail box just yet. When I feel I have learned Ubuntu enough, I will use it on my next computer as well, reverting this one back to what it is intended as: A server. Storage. With Ubuntu calling the shots.
