I think jolla tricked/trolled us all with non-keyboard-friendly UI just to suprise you all with a keyboard next summer. They now looking/working to find the best Keyboard munufacturer to deliver the next step of n900. Thats why they never showed us landscape. Either the phone don't work in landscape. That would make the phone unusble or the keeping it hidden to shock the world with a keyboard.

I really hope they are going for somthing creazy design wise like a discphone or something.

Only Chuck Norris knnows the answer for this.
