I buy a new laptop each year for work and am currently using a 2011 Snow Leopard Macbook Pro. However, replacing spaces+expose with mission control has made me wonder if the loss of productivity might make it worth waiting for the next OSX. Maybe they will make a better job of it next time. 1) Do you think the next OSX will appear on the 2 year cycle i.e in 2013? 2) Do you think apple will re-assess the interface options i.e mission control?
