I've just ordered myself a new laptop!
It's a Lenovo Ideapad b570, it comes with 4GB of RAM, a 500GB HDD and a 15.6 inch screen. (I'm going to add another 2GB of RAM).
It comes with Windows 7 preinstalled, but I'm going to install Ubuntu on it, and leave a 75gb Windows partition for gaming and using programs that I can't get to work through Wine.
This will be my first "new" computer, since all of my older ones have been hand-me-downs from my family.
I can't wait until it gets here!
