I'm not that surprised... They're not just trendy, but hardware wise pretty nice in terms of quality, appearance and battery life. I don't use it much, but my M1 Air that I got for personal use generally makes it through a week of use on road trips without needing to recharge. Hour or two of email/reading a day, about 60% brightness.
I think MacOS feels a bit old at this point, but the hardware is pretty nice for what's on offer in the mobile space. I may well go framework for my next laptop in a few years though.
I just bought my first Mac in ~30 years, having been all Windows or Linux in that period. I've been blown away by now nice it is - both the hardware and MacOS. Sure, there are some annoyances for a "power user" where something like showing hidden files requires an obscure key combo, but for the most part it has been a refreshing change.
It's also just blazingly fast compared to the similarly priced ~3yo Dell that it replaced.
I didn't realise Macs were a quarter of the desktop market.
