Free. It's a price we love. Ironically, free usually comes at a price. Today, that price, is the loss of Amazon's try-before-you-buy TestDrive service for Android apps. It turns out, with more and more apps being free (at least to download), there was less demand for a service that let you test 'em out in the browser/virtual machine. Makes sense. Accordingly, Amazon has pulled the TestDrive feature from the appstore -- this has no effect on any apps that used it, just the feature is gone. The downside being there's no longer a way to (easily) check out apps that don't use the free-to-play/freemium model on Amazon's store any more. But, coming full circle... that's the price you pay for having more free apps, right?
