Although Microsoft leaders have spent years promoting tablet computers with only marginal success, excitement around the form factor is finally building, thanks to technology advancements, Microsoft chief research and strategy officer Craig Mundie says.
"Bill and I and others at Microsoft have long been proponents of the tablet-based computer," says Mundie, referring to Microsoft founder Bill Gates. "We've worked at it diligently now for well over a decade."
Gates launched Microsoft's tablet PC platform in 2001, predicting that within five years the tablet would become the most popular form of PC sold in the US.
That didn't exactly work out. Tablet PCs are commonly used in some vertical markets, like healthcare, but they have not become popular in the mainstream.
But now, eight years after Gates' prediction, buzz is building for tablet computers. Persistent rumours of a tablet from Apple continue to circulate. Recently, a video emerged online of a slick hinged tablet device reportedly being developed by Microsoft.
Mundie wouldn't comment on that device, but he said that a confluence of trends makes now the right time for tablet computing. "Today, several factors are coming together that will probably make the concept more resurgent or at least become more mainstream," he says.
One technology development is that now a tablet device can accommodate both pen-based interaction and touch-based interaction. "The two technologies were generally not available together," Mundie says.
In the early days of tablet PCs, design was largely done around the pen because people thought users would want to use a pen to annotate documents and sign names, "and your finger was not pointy enough to do that", he says.
"But then of course came this whole idea of touch, which we pioneered a bit with Surface and got a big boost from the iPhone," he says. "People thought this direct-manipulation thing has some merit."
In addition, computing advanced such that hardware could be light enough to support all the features that people wanted. "I think it's a confluence of small, light devices with the hybrid touch and writing screen technology that will finally probably result in a tablet-type computer going mainstream," Mundie says.
