The integrated keyboard had a tab key, so autocomplete worked on the terminal. This was a really big deal that made the tiny keyboard much more useful for real work.
The Maemo distribution that the N900 ran was based on debian, and you could point apt to the standard package repositories to install pretty much any Linux software. This opened many, many possibilities - for example, I had an always-on computer in my pocket with WireShark installed. I could (and did) occasionally sniff wireless traffic to troubleshoot something. If you couldn't find a mobile app that would do what you wanted, you could usually install a desktop app and it'd work (though sometimes the UI was awkward on that small screen).
While most of the functionality can be replicated on a modern Android device, these pocket computers were different in a special way. The integrated physical keyboard, the tab key, the full Linux kernel and apt, all combined to create an experience that was distinctly different from Android. It really felt like a pocket-sized workstation - it was a full computer first, and pocket-sized second. Android smartphones are pocket-sized mobile devices first, and potential workstations second.
