Apple has all the hype with Retina Displays on their iPhone 4/4S and new iPad, but that does not mean Apple’s rivals are just going sit back and do nothing. Microsoft’s Windows 8 has proved to be quite the interesting operating system to watch, and if manufacturers are up to the task, they too, will be able to deliver hardware that supports Retina-class displays in the future since Windows 8 supports such high resolutions. Steven Sinofsky did mention that many Windows 8 tablet PCs will have pixel densities of at least 135 DPI, which is already superior to “HD tablets” that offer 1,920 x 1,080 pixel resolution on an 11.6″ screen that boasts a pixel density of 190 DPI. With “quad-XGA tablets”, however, these pack quite the punch with 2,560 x 1,440 pixels on an 11.6″ display, sporting a pixel density of 253 DPI. Does this mean it will be an all out war against Apple with new tablets that run on Windows 8? Only time will tell, all we know is, we will strap up for a real exciting ride in the years ahead.
