Absolutely yes and at least become familiar with other departments at your company. It will really make you appreciate the roles that sales, marketing, technical support, product management, professional services, accounting, legal, etc. play.
As for myself I transitioned from pure development into professional services (customer-facing post-sales installation, training, integrations, trouble-shooting). As much as I liked development I'm finding I'm really good at this role even though I consider myself an introvert. This group works really close with sales and technical support and I've learned a lot about those departments.
Benefits include: travel to exotic places, exposure to many companies (good networking opportunity), short-term projects with rapid closure, more time and brain energy to pursue personal projects, and very importantly: I'm no longer part of a cost-center i.e. when billable I'm making the company money! It offers some protection against off-shoring.
Drawbacks include: travel, no social life, and I miss hard-core development.
I realize that this may not be the path you intend to become an entrepreneur but relaying my experience for the benefit of others.
