The keyboard is a huge negative for me. Why would I want a significant chunk of my screen space taken up by a keyboard on a device that I'm aiming to use primarily for reading?
You missed out! The Passport was an excellent phone. Great hardware and the OS was nice. And the KeyOne (android) was probably my favourite phone ever.
Had you used any BlackBerry phones before it? In my opinion the Passport was considerably better than other BlackBerry phones from the couple of years before it, but it was so much worse than the older BlackBerries were (at least in the context of what was available at the time) so much better that people who had used BBs for years found the Passport frustratingly bad in comparison.
Yep, I had several Blackberrys and hated the Passport's weird, ramrod-straight 3 rows of keys. Much less ergonomic to type on than the slightly curved 4-row setup on the Bold 9000 (2008), which they never reproduced on future models.
