It was always a matter of when, not if, rivals would follow in Apple's
Longtime rival Microsoft
Mr. Softy has segregated the common sizes that Windows 8 will support into three primary device categories: slate (tablet), workhorse PC, and family hub. Some of these slate resolutions promise to give the new iPad a run for its money and its "resolutionary" (that tagline makes my heart cry) display. For quick reference, the new iPad sports a 9.7-inch display with a 2048 x 1536 resolution at 264 pixels per inch, or ppi.

Some of the higher-end Windows 8 tablets might include densities that go as high as 291 dots per inch, or dpi (same thing as ppi). A 10.1-inch screen at 2560 x 1440 would be 291 dpi, sharper than the new iPad, although short of the iPhone 4/4S density.
The software giant is also setting a minimum support resolution for developers to heed of 1024 x 768 (same as iPad 1 and 2). It laid out three primary reasons for doing so: (1) It's big enough to support the layouts that it expects from Metro apps, (2) many websites are already designed for that minimum so developers are familiar with shooting for that resolution, and (3) Microsoft's data shows that only 1.2% of current Windows 7 users have screens with resolutions smaller than that.
As of right now, there are no Google
This is more evidence of why Windows 8 can beat Android in tablets. Microsoft is focusing on areas that users clearly care about, and it has more experience with coordinated global rollouts than Google does, which include lining up all the hardware partners and app developers simultaneously.
