I had two BlackBerry devices for work, right about the time they were going away. I’d heard the keyboard was good on earlier models but it seemed like the quality had gotten pretty cheap on the later phones. The BlackBerry 10 OS on my last phone was actually pretty good, and probably would’ve kept them in the market if they’d launched it 5 years earlier.
I used a Palm Zire 31 and Later a Dell Axim 51v (Windows Mobile) in high school. People thought I was weird, but it kept me organized. I miss how simple and functional those programs were. This was largely pre-enshittification. No built in keyboard on either, but physical buttons alone are a strength.
