Here's an idea... What if we made a phone keypad in landscape mode, that could fill either the right half of the phone (for right handed users) or left half of the phone (for left handed users). I've already seen a picture of such a phone keypad in use in the landscape phone mode... All it takes is to add T9 to this and we can type our messages one-handed... Yay! Of course there is a danger of dropping the phone because its CG isnt centered at our hands unlike in portrait mode.

The other thing that concerns me is that the the all-too-important multi-task icon is at the TOP LEFT HAND corner. Sheesh... that means I wont be able to tap that button with ease when I'm holding my phone in landscape mode with my RIGHT hand

Perhaps nokia should learn from the mistakes of microsoft mobile (small 'x' icon on the top Right corner, and small start button on the top left') which were inaccessible with one hand, and take a leaf from iPhone (an accessible button at the bottom of the phone) which optimizes one-handed use
