Thanks for the input, guys.
I looked at the Carnegie Mellon program and it looks like a great one, but appears to be more geared toward the product management side of things. As for the the Berkeley program, I definitely want to keep it hardware centric, rather than media or software. I took a quick look at the UPenn program and it looks intriguing. Definitely going to dig deeper on that one.
In regards to getting a second bachelors, I know a guy who did ME and went to Academy of Art to get a second bachelors in ID, and he highly recommended that route. He said going with a second bachelors gives you the full ID spectrum of knowledge, which you wouldn’t get from doing a masters in ID without already having done ID for undergrad. I personally don’t want to go down that route, but I think it is a personal decision. Worked out well for him but may or may not work out well for others.
