I had issues as recent as last year's new products.
But otherwise I love the concept of hardware access with HTML. The embedded guy in me thinks the future is going to be crazy. I can't quite wrap my head around the possibilities.
I also keep Bluetooth disabled on my mobile devices. It's used extensively to ID and track people and their devices. For things that don't move and are only ever paired to a single thing (like a speaker) it works fine. Most of the complaints I hear about bluetooth are from people who pair multiple devices to a single source and want to easily switch between them.
