The MD&M 2015 Philadelphia Conference and Expo is October 7-8, 2015 at the Pennsylvania Convention Center in Philadelphia, PA. I've been to the MD&M Expo at the Jacob Javits convention center in NYC. It was incredible for its size and scope. If the Philly Expo is anything like the NYC expo, then anyone thinking of building a product now or in the near future should attend at least one day. The NYC Expo is so large it took me 3 days of walking and talk to people to cover every isle in 2014. It was highly illuminating. This year it only took 2 days. Also, participating in the speed networking sessions was a lot fun too.
