Battery life on my Varia is pretty decent, plus it can be run with external power if you're on a really long ride and you need extra run time.

It's quite likely that you'd be able to connect a Varia to your Garmin watch if it's a reasonably recent model. Then you could get radar alerts as vibrations on the watch.

Saw 600 in Shanghai a few years ago. It was horrific. Fortunately the Chinese government has made quite a bit of progress in improving air quality in the last decade so such terrible pollution isn't nearly as common today as it used to be.

Based on the decisions of the Premier and government of Alberta, it won't. 🙄

I live in China. I download movies and TV shows via torrents without a VPN with no issues whatsoever.

If you use Rufus you can remove that and all other hardware requirements and install 11 on much older computers than Microsoft intended.
