Steven Bristol (blog) is a co-owner of Less Everything. They pride themselves on writing applications that undercut their competition, focusing on writing good and useful features, not bloating up with more features. Definitely a 'build half, not half-assed' attitude. I had the opportunity to spend some time with him, and he was kind enough to sit down and talk about their philosophy on software development.
I'm using their product, Less Accounting, to keep track of my expenses/mileage/business stuff for the tour, and I'm loving it; it has just enough stuff for me to manage the essential information.
