New life situation has bring to mobile world totally. I am typing this with my Panasonic Toughbook CF-W7 with integrated 3G and running ubuntu 8.10. It's really like a breeze. Encrypted emails fly with thunderbird and enigmail. I did some research to replace this combination with Apple, no luck. Integrated 3G was missing and my experiences running thunderbird on apple is not so great.
So, being mobile is not so bad after all!
