4.8″ WVGA should be the sweet spot for more pocketable devices

Posted by Charbax – January 19, 2010

As you would know from checking out my other fansite http://archosfans.com I am a fan of the 4.8" 800x480 resolution screens. I just wonder why we still haven't seen any so called "smart phone" with such screen size and pixel densities. I posted this opinion at crunchgear:

5″ is about the perfect sized screen at WVGA resolution because it fits in mostly all pockets and provides enough resolution with large enough pixels to provide near full PC-like web browsing and movie watching experience. I also think that it can provide near desktop-like applications experiences.

Normally, even with a kick-stand like on the Archos, you will hold the 5″ Tablet at about half arms length from your eyes, while the laptop screen usually is nearly at twice the distance from your eyes down on your lap or on a table further away (also because you have the keyboard and mouse pad).

So basically, the Archos 5 Internet Tablet pretty much provides you 75% the full resolution experience of web browsing on a Laptop and 75% the experience of watching a movie on a laptop. In terms of number of visible and reachable pixels per degree of angle of vision.

While the iphone only provides you with 33% the resolution/experience in both browsing and video watching compared to a laptop. That is why most of the actual use of iphones and other similar sized smart phones are mostly for actually only doing phone calls and playing music and running random low definition apps (with few buttons and little screen size to actually use).

You may count screen size difference between 3.5″ and 4.8″ as “only” 1.3″ difference. Another way to compare screen sizes is the mathematical way, which is to say the truth that Archos 4.8″ screen is 2x the surface area of the iphone screen. Basically it is really a huge difference.

And I just don’t think it is right to say that 4.8″ screened devices don’t fit in most people’s pockets. Wallets and Passports are all larger than 4.8″ in diagonal and they are designed to be transported in pockets all over the world. Walking around with business card sized LCD screens is just not good enough in my opinion if you really care to take the Web and Video with you everywhere.
