I too will be going to Linux here soon. I just wish a Linux distributor would make an OS specifically for a desktop computer.
Let's face it, everything Linux makes is for server operations and is not specifically geared towards the desktop. Linux has a golden opportunity to gain a huge portion of the computing market, why don't someone take it?
You don't have to. "Cloud Architecture" enables you to do that if you want to, but you can create a "cloud" that only exists on your local system.
There are actually a number of those. Ubuntu, and it's variants are primarily aimed at desktop users. For a newbie Linux user, I'd recommend Mint. (Mint is a, ubuntu-based distribution) YMMV. As a newbie, I'd stay away from Fedora, which is my primary desktop, mainly because it really is the bleeding edge sometimes, and that's somewhere you really don't want to be as a newbie.
