Not interested.
First, battery life. Samsung says with fair usage, it will last a day. But you know how some of use get carried away with new gadgets. For sure we'll be using it daily and try to integrate the device with out daily lives and end up realizing that we are wearing a watch that wouldnt last us a day.
Second, connectivity. Yes, we have android phones but some of us dont use samsung (assuming that the gear may be paired with other samsung devices other than the Note 3). Some of us use phones by HTC, LG, Motorola, etc and even when we are interested, it isnt compatible with our device.
Third, price. 299 dollars is too much. I can buy a New Nexus with that money.
If it were to buy a smartwatch, I'd buy a Pebble watch or this new Kickstarter project called Kreyos Meteor (well, if it proves better than the pebble). Just my opinion on the matter.
