I love the spirit of vacation policies like this. Your results are far more important than how much time your butt's in a seat at the office. My only problem with it is that (at least in the US) you're not accruing vacation time. So when it comes time to leave the company, you're not going to get any sort of payout for that. I can't speak for everyone, but I can speak for myself and the people I've observed in various companies and startups: we don't take much vacation time. I don't believe I know anyone who has cashed out their time off in companies that have traditional policies. So, in my case, while I like Balsamiq's vacation policy better, it has turned out that the traditional style has been a better deal for me.
