Microsoft VP, Dan'l Lewin has told TechRadar in an interview that the tile layout in Windows 8 on tablet devices was conceived before the iPad was launched.
As reported by TechRadar:
"Think about when the planning started for what you saw just the other day; all the planning, the intent, the interface design work was done before the iPad hit the market," said Lewin.
Lewin also admitted that Microsoft needs to churn out its products faster:
"We know where we're going - we just have to get there faster."
It's always good to know your mistakes and correct them.
