Does bigger screens on mobile phones lead to better usability?

Screens on mobile phones is getting bigger. That is good because Jakob Nielsen says bigger screens leads to better usability. One reason mobile phones is getting bigger screens is that mobile phones just isn’t mobile phones anymore. They have become cameras, mp3-players and internet devices as well. All this new functionality requires a bigger screen compared to what is necessary for just making phone calls.
But even though i do agree with Jakob Nielsen that bigger screens leads to better usability, the usability is of course also depended of the design presented on the screen. As Buchanan et. al. state it in Improving Mobile Internet Usability one problem is that the design isn’t tailored to the screen size. Designers try to fill a sheet of paper even though what they are designing for is a Post-it.
The article The Myth of a Big Screen, Treating the symptoms rather than the cause state it this way:
“Making the screen bigger is just the current fashionable red herring to distract you from the plain and simple fact that the vendors can’t get the design right.”
These articles are from 2000 and 2001 and therefore im surprised to witness the new Samsung Instinct and specially the design of the browser on the Instinct.
But let’s first have a look on how Apple designed Safari on their iPhone. Both the iPhone and the Instinct have big screens. But they still have small screens for web surfing. To give the user the best experience it may be logic to use every possible pixel on the screen for content.
When scrolling in Safari on the iPhone the URL text field will disapear as you scroll down the page giving more space for content. But still there is 20 pixels used for the Status bar in the top and 44 pixels being used in the Button bar in the bottom.
I think it’s a good decision made by the Safari designers to let the URL text field disapear because on such a small device every single pixel used for content counts.
Therefore i was kind of puzzled when i saw the design of the browser on the Instinct. The Instinct as well as the iPhone has a URL text field in the top. Instead of a Button bar in the bottom, the Instinct designers have chosen to use space on both the left and the right side of the screen for buttons. This gives very little space for the content.
Luckily the designers have made it possible to enter a Full Screen View by touching an icon. The strange thing is, that a Full Screen View on an Instinct isn’t what i would expect from a Full Screen View. The only thing that disapears when you touch the icon is the URL text field leaving all buttons in on the left side of the screen.
The best aproach i have seen so far on designing a browser for mobile phones is Firefox. Though Firefox for mobile phones isn’t released yet a video shows how the Firefox mobile phone team have aproached the design challenge and have understood that on a small screen every single pixel used for content counts. All pixels are used for content which i think will lead to a better user experience than on both Safari on the iPhone and especially the browser on the Samsung Instinct.
To reach the navigation buttons on Firefox you have to scroll your finger to the right which reveals navigation bottons on the left side of the viewpoint. This aproach is very clever. Firefox use every single pixel for content which is what users are interested in when they read/scan pages.
It seems odd to me that the Firefox browser and the Samsung Instinct browser are designet the same year. The Safari browser does a deasent job but could learn from Firefox. But the Instinct seems to be designet before 2000 where the article mentionet at the top stated
“Making the screen bigger is just the current fashionable red herring to distract you from the plain and simple fact that the vendors can’t get the design right.”
It’s great mobile phones now have bigger screens which makes it easier to surf the internet on mobile phones. But to what use is the bigger screens when designers just don’t understand that we are not interested in their design but content?
