I also had an Enterprise Architect license, which I paid for myself - it's an impressive product. But what most people don't get about UML is that it works best as a documentation and explanation tool, not a design tool. I've never seen a project that successfully used UML (or other structured graphical languages) for design on a realistic (say 5 man year) project - it would be interesting to hear if anyone else here has, and even more interesting (and believable) to see the actual design.
Edit: reduced 10 man year to 5. 10 is too long & overmanned (though I have worked, unhappily, on such projects).
