As an Android user, it would be completely useless for me to buy one; I couldn't use it!
However, even if I did have an iPhone, I'd still prefer the Pebble Time, just for the battery life alone. I currently have a Moto 360, and it lasts about 2 days on a single charge (depending on how often I'm checking it/how often my girlfriend texts me). While that's over twice as long as the Apple Watch, it still doesn't hold a candle to the longevity of the Pebble.
