Another suggestion for a better keyboard:

Design a nice "blank" keyboard with OLED-lit keys which load the keymap from firmware upon boot, and which could of course be switched to another layout as desired, on-the-fly.

While such an OLED-lit keyboard might be slightly more expensive to build initially (although Nokia would definitely benefit from their economy of scale), there would also be significant "value-added" savings post-manufacturing, e.g. in terms of maintaining local stocks of said keyboards. Also, as a very large global company Nokia has to currently deal with a large number of different layouts and they still can't cater to many markets (including some very large languages/scripts).

Of course, the new standard OLED keyboard would also be naturally back-lit...

Open-source OS will also enable anyone to create keymaps (and translate the OS) without the "articificial" restriction of needing approved/manufactured fixed-key keyboard.

Wouldn't this kind of flexibility be a great Unique Selling Point?

On-screen virtual keyboards already provide the input flexibility, but at the cost of using most of the screen real estate in order to be useful. A customizable physical keyboard on the other hand...
