I love working in coffeeshops, drinking vanilla lattes and looking cool. My Dell Inspiron 17-inch widescreen monitor always attracts attention. Yeah, I enjoy the notoriety, and I get to tell people I'm being paid for my time, too.
It's a super cool laptop, but it's also a table hog. Those little bistro tables are totally dwarfed and my wife can't see me from behind the screen. She says it's like playing "You Sunk my Battleship!" with me, but far less social. :-)
In spite of this point, I do get a lot of work done. I try to follow my own Dan's Rules of CoffeeShop Laptop Etiquette, and to not to take over the free-spirited coffeeshop ambience with my technological terror of a work machine.
