A:AnswerWoah, stop the bus. The Acer website and representative are pushing the garaged stylus for the Spin 13. DO NOT BUY THAT for this computer. USI is supported by the 713, but unfortunately HP makes the only USI stylus available right now (google HP Rechargeable USI Pen) and it is almost always out of stock. Use something cheap or whatever you have at home for now, and wait to get a USI stylus. (Don't quote me on it, but Lenovo has made some noise about putting one out soon). My goodness. I bought one and I'm hoping it works properly so I don't have to deal with clueless customer support...
