There is no way I would pay over $150 for a smartwatch.
I bought my Sony Liveview for under $20 a year ago and this thing is great. Sure I can't send stuff from it, but for the price deally matter? I get texts, rss feeds, facebook and twitter notifications, can see who's calling, and can control my music player with it. I only charge it maybe every 3-4 days, the only issue is the screen doesn't stay on to show time.
Sorry Samsung but I would not buy the Gear even if it did work with my Nexus 4.
Now if someone would release a watch that does what mine does with better battery, voice input for texting (possibly calling if it doesn't look awkward), looks nice, is waterproof, and is not proprietary all for 150-200...
