I've only had a short time with 2.0.1 so far, but am already noticing that the watch face wakes quicker, apps load faster, and Siri is more responsive. It's really quite a difference. OS 2.0 was honestly a disappointment in some ways because of lag and glitches. If the performance I'm seeing in 2.0.1 holds, this is the patch we needed to really enjoy everything the watch has to offer. Please post your impressions of 2.0.1 in comparison to 2.0.
