Downside: you're meeting with a potential investor or client for your start-up and you've got to pull your laptop out.
Other possible downsides include, people coming up to you and bothering you with non-relevant "work" or "free work for equity" which you're not interested in.
There is also the exclusivity thing, where a potential client might perceive you as "too eager" for work, and you end up loosing a gig you might have gotten otherwise. (Granted, I'm reaching on this one).
I think it's a neat idea, but you have to be judicious when putting on any overt "label" on yourself or on the tools of your trade. I only bring this up due to my own experiences with stickers on my laptop. Getting them off is no easy task either (glue residue and such).
