My trusty AW2 (in Cocoa, which I loved, but is no longer available) dropped yesterday. Onto a hard ceramic floor. Face down. Watch face glass is completely shattered... thought it would be a little tougher than that... I prefer to pick one up locally if I could, but not sure about AW4 availability at my local electronics stores (no Apple Store where I am). So, my choices could be limited. There are some AW3 models floating around about $150 Cdn less than the base AW4 model prices. Apple Canada isn't listing much for refurbished AW models. Is the AW4 worth it? Compared to what the previous generation AW3 has to offer? What do people think of the new interface offered by the AW4 where complications look like they're curved in the corners? How is the AW4 at tracking/measuring activities such as calisthenics or martial arts? I really like the AW, but I'd seriously consider other brands and models (Samsung Galaxy? Garmin Fenix? FitBit?). However, I understand that no other smartwatch can reply to text messages or some notifications if I have an iPhone/iOS? Is that true? No other options? Thanks in advance.
