I agree that JamJar does work a little slowly, especially when you first create a new space. However, I can't necissarily agree with your statement about the appeal. I'm very pleased with the fact the Adobe sees that good looking applications are better than unappealing ones. As a developer who's audience is mainly high school students, it can be hard to impress them with dirty, crummy looking apps that you have to pay big bucks for. So the fact that I can use JamJar for free and have it look really nicely, I am definitely satisfied.
