= no comparison. For $100 you can get a fitbit. It does NOT much really. Just fitness stuff like heart rate, steps travelled, etc. Or get an Apple Watch for $349 that does all that and a H_E_L_L_ of a lot more. It can send/receive text messages, make phone calls, play music, act as a stop watch, pay for a purchase, get you into your hotel room or building (hey no more access passes), START your car and do almost ANYTHING else an APP developer can dream up!!!
These naysayers don't get it. This is going to be a killer device once people realize how useful it will be. And after a few iterations, it will only get better. The battery life will be way better as time goes by. charging nightly is fine. We all do that with our phones already. It'll get better for sure though. Remember the first iPhone. What a piece of #$%$ it is now, right? iPhone 6 is 100 times better. Well Apple watch 3 or 4 will be 100 times better as well. Got to start somewhere though. That;s why I will start with the cheapest one for now. $349 is a steal really. If I get a year or 2 out of it, great. I'll toss it and get another one in a few years when it's even better.
