One thing about the Nokia N900 (Maemo) system has always bother me. And that was it’s dependance on operations in Landscape mode, usually with the hardware keyboard extended.
Often I have heard other potential buyers put this restriction as a deal breaker. And while the Phone DOES operate in Portrait mode (in fact it switches to the Phone application when in Portrait mode) it could not operate the other applications in Portrait mode. This issue was also due to the lack of a Portrait virtual keyboard. Most of the complaints I heard were that people would use one handed operations while the phone was in Portrait, and that the N900 was flawed if it could not.
Now, watch some YouTube videos some time, if you watch other phones in operation, particularly when using their virtual Portrait keyboards, it’s never one handed. Almost without exception, the user brings both hands into play holding the phone with both hands. This more or less renders the argument moot if the user always uses both hands. The N900 in Landscape would be equally operated with both hands, and in fact be easier to use with either the larger virtual keyboard, or the hardware keyboard.
Problem, and flaw, resolved. By human behavior.
