Completely agree on the curved keyboards. BB Classic was the last proper one and I loved it. Android app compatibility was spot on as well, where it failed, not to RIM's fault, was that you had to hack around google play services, and as a result, apps that did "device security checks", like banking apps, failed.

One notable app that also failed this way was, the irony, the Work suite, soon owned by... BlackBerry. My dear employer dropped BES support and moved to Work, which didn't work on BBs after some time, and that was the end of it (BBOS) for me.

Only BB did it right, but - and I don't know to what extent - it still sits on some amount of IP/patents that cover the doing it right.
