Retina display is only a good idea on phones
There is a new rumor that Apple are planning retina display level screens for MacBooks next year, or at least MacRumors reckon they might be because there are hints of it in the beta of the next update for Lion. The retina display is currently just used on the iPhone and iPod Touch and puts the screen resolution so high that it is impossible to tell the difference between individual pixels at a certain viewing distance. The new displays have been a huge success and helped to maintain Apple’s competitive advantage.
When rumors for the iPad 2 started circulating around this time last year one of the first things to crop up was the possibility of the iPad also having a retina display. Some people thought that the screen would change shape from its standard 4:3 ratio to a full HD screen at 16:9. Needless to say, it didn’t. Similar rumors have also been appearing regarding the iPad 3 however the common decision is now that the iPad works at 4:3 and there is no need to change it to 3:2 or 16:9 so any change would likely be to double the resolution.
The emerging rumor suggests that MacBooks could have their display resolutions doubled from 1440 by 900 on the 15″ model to 2880 by 1800. It seems perfectly reasonable that Apple might do this and the hardware could probably just about handle but the problem is that there isn’t much point. It would put the resolution on the 15″ screen (it is worth me pointing out now that I am using a 17″ screen at 1440 by 900 at the moment and there are absolutely no problems) higher than Apple’s 27″ Thunderbolt display which is only 2560 by 1440 pixels and it operates very well at that resolution.
Despite being quite cool there isn’t actually any useful purpose in producing a 15″ laptop with a higher resolution screen than a $999 27″ high-end monitor. The first major problem would be that it would hinder graphics performance unless AMD or Intel have some secret that they are launching in the New Year. The second is that there isn’t really any content designed for such high resolutions. I’ve never seen video higher than Full HD on the internet (I know that YouTube does go up to 4K though). Graphics intensive games generally don’t go beyond full HD. Designers don’t really need high resolutions either because a useful feature called zooming exists.
Perhaps I’m being pessimistic, but there really doesn’t seem to be anything useful in a 15″ laptop with a really, really high resolution screen.
