The "thinner" is a thing that tempts me to upgrade. Thinner means lighter: I live in the middle of a very walkable area. So I walk a lot. It is great to be able to throw my computer into my bag and go out to work in the middle of a park or wherever; my computer plus my drawing tablet is only slightly more weight to haul then a hardbound sketchbook. I think the new machine would cut it down to about as much weight. It is pretty cool to go out carrying everything I need to do my job and only carry about six pounds of stuff on my shoulder. And that's including the bag I keep the laptop in, plus wallet and suchlike. Thinner means style: In general, things that are slim are also things people see as "elegant". Back around 2000 I carried a Handspring Visor Edge in my pocket rather than a clunky plastic Palm Pilot, not because it was any more powerful, but because it was a sleek little piece of shiny metal that made me happy to hold in my hand. There's a point where there is Enough Battery. I can take my 2013 Air out for a day of rambling around the city and drawing wherever I feel like stopping, and not worry about it running out of power as long as I charged it last night. I think the new Macbook has a lower estimated battery life than my current machine, so that's a downside of it.
