I had Ubuntu Natty full configured and working on the SSD drive in my Lenovo X201 Thinkpad.
Then I got a Lenovo W520 Thinkpad, which I'm sure has different wireless card and graphics card and other things.
I popped out the SSD drive from the X201 and put it into the W520. This SSD is the master/boot drive and also holds all my data. I turned on the W520, and to my surprise, everything just works. Is this to be expected? I don't need to do a clean installation?
In other words, is Ubuntu generally installed on a hard drive in a way that make it portable across different Thinkpad models and configurations?
