Re: Sadly, I predict failure
The same thing when you want to use an HTC Desire Z and its keyboard in portrait mode, I'd expect.
(I have a Priv. I simply don't use the keyboard as a keyboard in landscape mode. You COULD, but it's awkward as hell. You use it as a trackpad when the phone is in landscape. But frankly, the only time I type in landscape at all is when a game forces landscape and you have to enter a username or something. Even my SSH client I run portrait, 80 columns by 62 rows.)
I'm still bummed there's no BB10 version of the Priv. I vastly prefer BB10 to Android, and I can even deal with BB10's lack of apps, but I wanted a bigger screen than than my Q10, and the Passport was just a bit TOO weird.
