Julie Larson-Green spoke with MIT's Technology Review and when asked if Windows 8 was developed as a touch-friendly OS in response to the popularity of iOS and Android, she said don't be silly, it was all Microsoft's idea with no outside influences whatsoever.
"I only saw the iPad after we had this design ready to go. We were excited. A lot of things they were doing about mobile and touch were similar to what we'd been thinking."
"We [also] had differences," she added.
"We wanted not just static icons on the desktop but Live Tiles to be a dashboard for your life; we wanted you to be able to do things in context and share across apps; we believed that multitasking is important and that people can do two things at one time."
She also went on to say that she "can't imagine a computer without touch anymore" and she believes that the vast majority of future PCs will be touch-enabled, while adding that "a finger's never going to replace the precision of a mouse" so there will always be hybrid options too.
