Classic Bluetooth was very limited in scope and very power hungry. That is what limited its adoption. On the other hand Bluetooth low energy is much more capable, useful and affordable. Now that there is a sizeable population of BLE iPhones(4S+5) in the wild, more manufacturers will be targeting it. Watches, wearable devices, health equipment, door locks, speakers, appliances, toys, etc.
