Yup, I use Laravel (was a tough choice, it's new but the features and speed benefit make it worth the risk plus it's open source and built on symfony to a large extent which is going nowhere) but my application is mostly decoupled from it (Uncle Bob Martin style).

I could (relatively) painlessly move to another framework (particularly Symfony2) the only major pain point would be the Eloquent ORM but as I've wrapped all that behind repositories the interface would remain consistent.
