I also recently bought one (~3 months ago?). My main reason for getting the machine was the small weight and size. I'm a fairly small person with small hands and like to travel extremely light for work (which is very often).
The keyboard was my biggest concern since I've been touch typing most of my life.
The v2 butterfly keyboard are a marked improvement over the first gen. The first gen was very difficult for me to type on due to the small key travel -- it felt like I was typing on glass.
With the second gen, I did a lot of in-store testing and speed tests. My speed only dropped to like 80-something WPM from my normal ~100 wpm. Within a few hours of owning the machine, I was pretty much back to full. (Their return policy is also something to keep in mind if the keyboard concerns you)
It increasingly has become quite possibly my favorite keyboard ever. I'm even unashamed to say that I prefer it over my mechanical keyboards. Never thought I'd say that about a laptop keyboard. Obviously down to personal preference.
I'd say if you haven't tried the v2 butterfly keyboards (can't speak to the v3), try to give them a test with an open mind. Do a couple typing tests. Type as close to normal as possible (both speed and subject).
> whether you use it much for text input (such as emails) or programming
I use it extensively (>8 hours a day) for programming, emails, and chat. The only thing I don't really do with it is play games (not exactly a gaming machine).
For some added background, I also used an Acer Aspire One 522e netbook running Linux for a few years (this was a while ago), so I definitely have some abnormal tastes when it comes to daily driver machines.
Overall, the only thing I'd change about this laptop is I'd swap out the headphone jack for another USB-C port, but even that isn't that big of a deal (to me).
