Seriously. Are you serious? Has not the iPhone/iPad taught you its all about the apps.
You seriously think Tizen will ever have even a fractions of the Apps the Watch will have? Samsung is having a hard time selling 1 million units a year. You really think App makers will waste time writing Apps?
All 3rd party Apps being slow is a myth. Dark Sky runs real fast on my Watch. And so does ESPN.
The lack of Apps is a deal breaker for many on the Samsung Gear.
On Samsung you get a choice of 1 or 2 apps for category. For Apple Watch you get 20 choices. Plus much better quality. Not to mention the Apple native Apps blow away the Tizen ones. Apple Pay, Siri, Apple Music, Activity, Messages, ect. Where's my quality sleep trackers on Tizen? Or weather Apps? Or score Apps? Boarding pass apps? Digital payment Apps for trains? Podcast Apps? Camera Apps? AppleTV remote?
Buying the Samsung product is painting yourself in a corner of very limited App selection. And we know how well Windows phone did with limited Apps.
