I'm strongly looking into transferring to the Koln International School of Design (http://kisd.de/home.html?lang=en) which is in Cologne, Germany. (I'm currently a sophomore at a US non-design school.) It's a unique program that basically covers every field of design; the major is called "Integrated Design." You essentially choose your own curriculum.

It really comes down to what sort of design you're interested in. US schools tend to be focused on 2 subjects, with not much else: industrial design and communication/web/graphic design. Different schools are better at different things, but to highlight a couple:

Carnegie Mellon: strong in communication design, interaction design, Human-Computer interaction, and generally anything computer science related.

Cincinnati: not so great of a school in general, but the design department is top 5 in the country, mostly because the program requires 4+ co ops (internships.) Supposedly they're pretty good at traditional product/industrial stuff.

I decided to pass on design school a few years ago, mostly because I didn't want to be pidgeonholed into either of those subjects.

I'm pretty familiar with design schools, so I'd be glad to answer any specific questions. Also try http://boards.core77.com
