I use it for Illustrator fiddling and InDesign work. It's handled everything I throw at it, from shit infographics to shit giant reports, as well as some silly complex .ai docs (big maps, lots of objects), but as +soul says it won't replace a full time pro machine (my eyes aren't good enough for the tiny screen and I can't plug it into my ageing yet still lovely thunderbolt display)
My pro does its time templating/setting projects up and then I use my MacBook on the go/weekends away/etc to fill in the blanks. My pro hasn't left the house since I bought it. I love the little thing's form factor, perfect as a travel/on-site machine.
