Yes, I had a programming dream last night. In the dream I was able to solve a complicated programming problem that I couldn't seem to figure out during the day. Isn't it funny how our brains work? Now I just have to convince my boss that I'll be more productive if I sleep at my desk.

Basically MCPD is the new MCSD. MCSD certs are geared towards .NET 1.x developers. If you are using .NET 2.0 or above you should consider one of the MCPD certs: Windows, Web, or Enterprise. IMHO, certs are nice to have but not required. Remember, there is no substitute for experience. You can be a proficient or even expert .NET developer without any help from certifications. But if you are a less experienced developer, and new to .NET then becoming certified will help you along the learning curve and MAYBE help you land a new job. I used many different sources to prepare for my MCPD: Web. Here they are in order of importance: Experience(real world and experimental), MSDN/Web, Professional ASP.NET 2.0(WROX book), Measure Up and Self Test practice exams, Instructor-led course from HOTT[^], MCPD Self-Paced Training Kit, and the MS Study Guides.
