There is absolutely a value in it. I'm using my phone mainly for communication and I could kill for a physical keyboard, especially for a vertical slider like the old Blackberry Priv.

There is the F(x)tec Pro1X [0] which looks similar to the Nokia N900. It's a little bit too expensive for the specs (about 740€ for the 8GB/256GB version with Snapdragon 662), but could be a nice phone.

Or maybe OnwardMobility will succeed and release the new Blackberry this year and it won't be a piece of crap. /s
