This device will be one of the most dropped devices evah' unless they get the portrait mode ASAP. Yes, the current tablet community that uses the device will be more careful, but people used to smartphones will try to use the N900 one handed in landscape. Doing so is counter-intuitive and will result in Mr. Gravity breaking people's hearts. With one hand, hold a phone in landscape mode and portrait and see which way you are most likely to drop the device.

I still do not get how Nokia missed this and are now jumping through hoops to add it. A basic smartphone has the function of texting with one hand- in portrait mode and for that matter. Heck, most allow web browsing in portait too.
