I still need a truck.

Shawn Blanc says his iPad is now is laptop. Patrick Rhone of Minimal Mac agrees and even wrote his latest book all on an iPad.
To be clear, Blanc used to be a print designer and now writes full-time on his own site. I understand how it’s possible to be a writer and use just an iPad for work.
For me, I’m a web designer and rely heavily on my laptop to be productive. When I travel, it’s with 3 devices – my iPhone, my iPad and my MacBook Pro. While I am more senior at this point in my career and don’t find myself doing as much heavy lifting in Photoshop and Illustrator, I still need to use them.
I would love to reach a point where I just need to carry my iPad, but I still work on the farm and I need a truck (see also here).
