Mobile Phone Design Challenges...

So what are the challenges

Facts.

1. Typing on a soft keyboard is not ergonomic at all. Hard keyboard is required "qwerty" or otherwise
2. The "qwerty" (if there) keyboard should have buttons big and wide enough to make typing ergonomic.
3. Screen has to be wide so browsing, emails and other icons can be fitted into the screen comfortably

Challenges:

1. How do we fit in the keyboard and a wide screen into a phone and keep it compact.
2. How do we make it look sleek so it sells. Nobody would want to buy a clunky phone.

Attempts:

1. Nokia Communicator: Too clunky.
   
2. Sony Ericsson P800: No "qwerty" keyboard, but pretty promising
   
3. Sony Ericsson P910i: "qwerty" keyboard too small and un-ergonomic to be useful.
   
4. Sony Ericsson P990i: Very Very Promising. Reduced screen size, but "qwerty" keyboard very ergonomic, though not any bigger.
   
5. HTC Touch: No "qwerty" keyboard, but with the touch flow and wide screen, pretty good
   
6. HTC Touch Dual: Getting closer. Slider "qwerty" keyboard and touch flow makes it ergonomic, compact and sleek.
   

And the best ones until now:

1. HTC Tytn II: Full Slider "qwerty" keyboard, big enough to be ergonomic to type in long emails, sleek and compact enough to sell and Windows Mobile OS makes it Hot cakes.
   
2. Sony Ericsson Experia X1: The "arc slider phone" the "arc design" means the side screen slider. Not only does it make this phone the most ergonomic and fully featured phone, it has 2 main edges. It is Super compact and sleek (The geek value, the gizmo touch, et al) and Windows Mobile. Yes Sony Ericsson comes out with a phone with Windows Mobile 6.1 for the first time.
