Yeah I think I would have liked one too. It's just that when the passport came out, blackberry OS was already on its way out so I didn't buy it
The Passport keyboard had an ortholinear shape. Together with the overall form factor, I can see how people may have found it a bit form over function. But I loved it.
Maybe they made good stuff too but that put me off HTC forever.
For productivity apps, nothing compared with the Bold 9900. So snappy and minimalistic. The memos, calendar, messaging and the like were great.
As far as BB10 devices go, the Passport had the screen real estate, but the Q10 was way more pocketable. So I found the Passport awkward to deal with when on the move. I still have all of them. Who knows what to do with functional old tech?
