I plan on switching over as well. I love the speed when using static files, plus there's a couple of plugins that make this a full CMS like a CSS minifier and a thumbnail plugin.
Congrats on switching. I switched about a year ago and get a lot more delight from my elegant Jekyll setup than a convoluted WP install with thousands of LOC I don't need.
+1 on Jekyll. I've been running my primary site (http://personalmba.com) on Jekyll for six months now. No regrets.
