Some add-ins didn't really excite me. The ability to resize the split-screen, which lets you do more than one thing at once, lacked pizazz. On the Acer and even Microsoft's own Surface Pro, you can only split the screen in two, and only at fixed intervals. With the update, the screens can be half-and-half or roughly cover one-third or two-thirds of the screen, instead of one taking up a sliver as in Windows 8.
Another feature is a predictive text function. Windows 8.1 offers up three predictions for words you are typing on an onscreen keyboard when in certain apps like Mail. To me, the feature seemed to be more annoying than useful, even though you can select the options with sideways swipes on the space bar.
Yet another feature turned the camera into a motion detector. In one demo, Microsoft's new "Food and Drink" app lets users swipe through a recipe with mid-air hand gestures. In practice, this often failed, sometimes turning pages in the wrong direction or not reacting at all. Still, it's a way to struggle through a recipe if your hands are coated with sauce.
At Wednesday's presentation, Microsoft executives previewed future Windows functions that could come in handy, including voice recognition in apps and contextual understanding of spoken questions.
For example, corporate vice president Gurdeep Singh Pall demonstrated a prototype travel planning app that not only showed 3-D overhead views of cities but gave computer-voice tours of various monuments. Speaking the question "Who is the architect?" brought up a webpage showing the answer, simply because the building that the architect designed was in view in the maps app."Apps are going to have eyes, they're going to have ears, they're going to have a mouth," said Pall.
As of this month, Microsoft says its new Windows platform will have 100,000 apps, and the company made it clear it hopes developers make even more, incorporating some of the new tools it has made available to them.
Ballmer said in his keynote he hopes that Windows 8.1 also offers a "great path forward" for users of the millions of programs that work on older versions of Windows. By showing off a variety of enticing features of the new interface, however, it's clear that path leads through the "Modern" world.
