I ordered ultra 2 yesterday, upgrading from series 6. While not aesthetically different, I think the new chip is a more important upgrade, and I will definitely use the double tap. Also looking forward to swipe/type texting now, esp on the bigger screen. Took advantage of my brother's apple f&f discount and used apple card so ~20% off which also made it a no brainer. I don't think the watch needs to compete with Garmin, etc for long ultra runners, but to me, training for a marathon, the 6 is currently needing a recharge after 10+ mile runs to make it through the day. This morning I did a 10 mile run, listening to music, and it drained into the red (18%). Would have been dead by 2/3pm with normal work use. Longer runs have and will definitely kill it, and last thing I want is to worry about it dying on a long race day. The ultra will solve that for me, and is for sure a valid upgrade. Even if I didn't have the discount I'd still probably buy it for the new chip too, because they will likely continue to use and develop for this chip for several years to come. I could see the earlier ultra becoming less useful/obsolete faster.
