I can’t recommend another excellent free ebook enough: Zen of Palm.

It accurately describes the key differences between designing for desktop and mobile, which explains why PalmOS was so much easier to use than the various Windows-based mobile formats from Microsoft at the time. I even wrote a whole blog series about this book two decades ago (https://dingyu.me/blog/zen-of-palm-1).

I switched from a Dell Pocket PC to a Treo 650, and it was such a revelation. IMHO, this little phone is still one of the best in terms of simplicity, even today.

My wife still misses her Centro. She held onto it until Google Maps removed the API that the maps app on it used.
