Microsoft isn't pulling any punches with its two tablets. On paper, they give Apple something to think (worry?) about.
Microsoft did not skimp on specs for its new tablets.
More than any single feature, the 3mm-thick Touch Cover (see photos below) stands out. Using pressure-sensitive technology, Touch Cover senses keystrokes as gestures, allowing faster touch typing than is possible with on-screen keyboards, Microsoft claims.
The Touch Cover attaches to the tablet with a built-in magnetic connector, "forming a natural spine like you find on a book, and works as a protective cover," Microsoft said.
There is also an option for a slightly thicker 5 mm Type Cover that adds moving keys for a more traditional typing experience.
Apple doesn't offer anything comparable. Though there are plenty of third-party keyboards.
And speaking of not comparable, with Surface, Microsoft is really trying hard to bridge the tablet-laptop chasm. Apple is not (at least, not in the sense that Microsoft is). By all appearances, Microsoft's cover/keyboard may be one of the best efforts yet, especially when combined with a high-performance Intel-based Windows 8 Pro tablet.
Other attributes like VaporMG casing -- which is very thin yet strong -- could also give Apple something to chew on.
