I have gone the other way and no longer travel with any laptop at all. My iPhone does about 85% of what I need to do and my Kindle PaperWhite does the rest (carry documents etc.)

In fact I am now searching for a super light weight carry on bag so I can achieve my One Bag dreams. Yes, I do favor Red Oxx bags but in the heat of the summer, I want to cut the weight even more.

(confession: yes I am bag hunting again).
