Something I whine about a lot is that the Bose QC45 is one of my least favourite device upgrades ever. I owned a pair of QC35 II's and I loved them, but I had an opportunity to get the QC45s through my work and figured it'd be nice to have USB-C, so why not. The QC45's are exactly the same in pretty much every way with the exception of USB-C — not an exciting upgrade, but whatever, boring is fine if they work well. But they inexplicably decided to remove the mid-level noise cancelling option that the QC35 II's had. That was an option that would essentially turn down the sensitivity a bit for windy conditions, which I need to wear the headphones outside. On the QC45's, there's only full noise cancelling or off, both of which result in enormous amounts of noise if there's any wind, making them completely unusable outdoors. I've reached out to Bose a few times just to try and understand the decision, but they've never even replied to me. It's a shame, because the QC series are the most comfortable headphones I've ever worn, but I can't justify buying anything from Bose again.
I've been using Notesnook for nearly a year and I'm really happy with it as well. Very feature-rich and easy to use despite a focus on security. I had a scare recently with an important note seemingly disappearing, and I was saved thanks to a really nicely implemented note history functionality that I didn't even know existed.
I will say that some of the design decisions can be a bit confusing, so it's worth testing it out before buying. Even a year in I find myself a bit thrown off by how exactly the relationships between notebooks, topics, tags, etc are expected to work.
