Lala.com is another one. They’ve been through a couple of business models before finding the great one they’re currently built on. They have a beta process that results in quick, consistent development, all while listening to user feedback. It’s legal music that’s cheap, and variable album pricing has the appearance of getting cheaper. It’s quite addictive; just today I heard that someone was thinking of making the switch to entirely digital music (no more CDs) because of how easy and great Lala makes the user experience.

One that might fulfill all of the ideas would be Gmail. It’s constantly getting better, features are typically fully developed before they’re released, feedback matters, the Labs features and themes offer great customization and the speed at which you can manage your email is awfully addicting. And while it’s hidden, even the high-end pricing plans have increased in space (250gb/$500.00 is now 400gb/$500.00), which is nearly as good as decreasing in price.

I’m sure there are more, but I’ve yet to craft something I’d put on this list. I’m working on it, though.
