I've had my watch since launch date and I've forgotten to take my phone to work 4 times now. Although pretty stupid, I feel like this is a good indication of how much value I find in using my watch and how its changed my approach to notifications and the amount of time spent on my phone. Anyway one thing has confused me. Having forgotten my phone I have still managed to receive iMessages to my watch, even though the watch is indicating that it isn't connected to the phone. Im assuming this is because my watch is remembering wifi networks it has used to stay in contact with my iPhone. Quite surprised that this is the case, seems the watch isn't so lost without the phone!
