I <3 Neelie Kroes. She's the first EU competition commissioner I've seen that takes her job seriously, rather than paying lip service in public while being a tool of whichever national government wants protection for their special industry.
In the US most people only hear about her when she slaps a big fine on an American company, but she's been making a lot of waves in the EU for actually walking the walk instead of just talking the talk. The Economist has covered her extensively, with a sort of disbelieving awe.
