I am a serious runner (have run 3 marathons, running a fourth in a month and a half), and I'm entertaining the possibility of converting over to the iPhone + Apple Watch. For me though, it's more complicated. I always run with my phone & wallet for emergency reasons. I don't use a sports watch anymore (I do have a Garmin), but largely due to their bulk & wanting to focus less on my time/pace & more on my body. I also am getting sick of Verizon getting vendors to lock down Android phones AND forcing phone vendors to toss a bunch of crapware onto the phones. The only reason I haven't switched yet is because I am on a legacy $40/month/line family plan. I am not a huge fan of iOS - I love Google's integrations with its services with Android. A lot of what I end up doing is taking out my cellphone to check for messages or the time. It's excessive, and quite inconvenient. Why not one of the existing smartwatches? I haven't yet been convinced that they're built for my desires. I'm not really in a rush to make a decision here, and likely will wait some before jumping in (probably will try out the Moto 360 in the short term), but the cost isn't really out of the realm of reason necessarily to me.
