I'M VERY GLAD YOU LIKE IT. OVER TIME, YOU WILL LEARN TO LOVE IT.

Anyway, what do you mean by not being able to move windows across desks? Ubuntu does this by default. Could you explain a little more about the situation?
Also, there are lots of undocumented commands that do cool things. Try these two.
1. Press Windows+E.
2. ALT+F2. Type in "gegls from outer space".
Now there are lots of things to discover about Ubuntu, like customizing it(which you must do), getting cool applications, and learning more. Following a good Ubuntu blog will keep you up to date with news and some cool tricks and software for you. omgubuntu is my favourite, you might like it too. You should approach this in manageable chunks.
Some quick tips.
*Learn to mess with all the settings on your computer. You might find something useful.
*You can customize the cool effects on your computer. You've probably seen the orgasmic floppy windows effect when you drag, right? The program that manages these cool effects actually has a huge control panel of cool effects you can choose.
To install it, open a terminal by going into Applications>Accessories>Terminal. Type:
gksudo apt-get install compizconfig-settings-manager
Once it's installed, press ALT+F2 and in the text box, type in ccsm. The control panel will pop up, and you can have fun finding the best settings for you.
*You have two toolbars(called panels), one at the top and one at the bottom. Personally, I enjoy minimalism. My desktop shows this. With some good customization, you can make Ubuntu even more kickass than it already is.
See? No icons on my desktop, the only panel I have(the one with the big e in the bottom left) autohides, and the dock at the bottom of the screen does the same. And a sexy wallpaper :3
but you'll get to this level of cool soon.
