Not just Silicon Valley–it's a West Coast thing. Go into any hip coffee shop in CA, OR, or WA, and you'll find a sea of MacBooks covered in stickers running brightly colored IDE's (and at least a few running vim).

The stickers are usually souvenirs from tech conferences, employers, cool startups, and hackathons.

But hey, most developers don't sit in coffee shops :) they are sitting in offices, mostly working on proprietary software that is making hundreds of millions of dollars per year for the company.
