Tonight, I attended an MBA open house at a major local university. It was interesting to hear about all the different types of MBA programs they offer. Some are part-time, others are full-time. Some require on-campus classroom sessions, others are 100% online. Some are exclusively for senior-level executives (executive MBA) while others may be very specialized for certain sectors (such as an MBA in pharmaceutical management).
I've been researching business schools for several years and I don't know when I'll apply, but at this point I doubt it will be in 2010 because I simply have too many things going on in my personal and professional life. However, maybe 2011 will be the year when I apply for b-school.
If you're considering business school, start by attending an open house. Then, you may wish to even sit in on a class session and meet current students, alumni, etc. An MBA can open many doors of opportunities if you go to the right school and if you leverage your network strategically.
