I develop for Android and have nexus devices, but my carry device is a Lumia 521 I got for $69 USD. Small & light enough to run with, smart enough to have a decent web browser / email experience - but simple and "just works". T-Mobile wifi calling is great too. I'm bummed the successor (Lumia 530) is fatter though. I'll keep my 521 until it no longer works. At $69, this is a pretty amazing device with Here Maps & Here Drive offline mapping and navigation.
