I have a Steel 3 and got my sis an 8 when they first launched for like $330 through Best Buy CC discount deal. She gave me her 5 since I wont upgrade until I see something worthy. The 5 works fast. Much faster than the 3 and I only use it for sleep tracking and working out. Dont feel like upgrading even at the $250 BB clearance on the 7. These prices are kinda crazy for a calorie tracker or distraction tool. If Apple gives me a light 1.5 day battery watch, I'll get it but it needs to last 1.5 days with my 1500 cal a day workouts and needs to be light. Other than that, im not spending iPad money on a watch.It says a lot that I have a series 5 and I see no incentive to upgrade.
