Hi there, I had several BlackBerry phones, including a Passport SE.

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?
