Here is my list. * Things work a lot more slowly in big co's. * There's a lot more ego involved so prepare for a lot of ass lickers(I really can't think of a better term). * A lot of "meetings", "discussions", "planning" and so on, which often are just means to kick a can down the road. * More time to relax. * Nearly impossible to change the status quo, not impossible but a very slow and painful process. * Often more freedom to experiment with technologies and proprietary solutions if you find a way to justify them(which is often not a difficult task). * Plenty of ways to squeeze out training, seminars, certifications and whatnot, just make sure you read the tiny font at the bottom.
