"In Steven Sinofsky’s thesis of Windows on ARM (generically dubbed WOA) published on the Building Windows 8 blog today, two photographs of an early development build of Windows running on prototype ARM hardware dates the effort to as far back as 22 January 2010, almost a week before iPad’s announcement on the 27th. Although Microsoft waited almost a year later to reveal WOA for the first time in public at a CES 2011 press conference, it’s now clear Microsoft too had future bets on an ARM-based ecosystem even before the iPad began selling and ARM took the spotlight for tablet devices." - LANjackal
