What the iPad 3 Looks Like
redletterdave writes "If you were expecting a radically different-looking tablet from the iPad 2, prepare for a minor letdown. In the same way Apple upgraded the iPhone 4 into the iPhone 4S, the exterior of the iPad 3 mirrors that of the iPad 2, despite completely renovated and upgraded innards. iLab Factory reportedly provided Sharp with the necessary parts to build the high-resolution iPad 3 display, and in a company blog post, various iPad 3 components are displayed alongside those of the iPad 2 for quick comparison. In addition to a new camera mount that will reportedly match or improve upon the 8-megapixel camera system in the iPhone 4S, the post also revealed that the iPad 3 will be approximately 1 mm thicker than its predecessor to house Apple's upgraded components, including a bigger battery, an improved camera, and a dual-LED lit system to make the 2048 x 1536 display even brighter."
Anyone who has ever written iOS software knows that the UI scaling is done by float, and can easily take a value of 1.5.
It can technically be done, but results will look like crap, because scaling of bitmaps does not look well if you don't use an integer factor - either you get some pixels larger than other, or you need to use interpolation, resulting in an altogether blurry picture. There's a reason why Apple did 2x upscale with iPhone 4, rather than going for the then industry-standard-already 480x800.
Besides, from TFA, it looks like they have already identified the specific LCD screen that looks like it's tailor made for iPad 3 in dimensional terms - and it's 2048x1536.
Like it or not, Apple basically defined the tablet market, and their hardware + iOS ecosystem is incredibly profitable. Like it or not, Samsung is perceived as a major clone maker -- the 21st century equivalent of Compaq in the late 1980s.
That was once true, but desktop and laptop screens have regressed over the past few years towards 1080p (high-def TV) resolutions. There are only a few 2560x1600 desktop displays now - Apple for example no longer sells one. 1600x1200 screens were available on laptops for some time, too, but no longer.
With that resolution and dual backlights, I bet the new iPad screen will look fantastic. Now give me a 'retinal' 30" display for my desktop, please.
