In a note to clients issued Monday morning, Canaccord Genuity’s T. Michael Walkley said — as reported by “Fortune” ( — that Apple’s iPad may outsell its nearest rivals 4-to-1 in 2011 as Android tablets “struggle.”

“Given the iPad’s time-to-market advantage, superior user interface, and leading application ecosystem, we believe Apple will maintain both market share and value share leadership in 2010 and 2011 for this new product category,” Walkley told clients. “Based on leading content for its iPad device, we believe demand for iPads will likely remain ahead of Apple’s ability to supply iPads in [the second half of 2010]. Should iPad production continue to ramp, we believe our 13.4M estimate for 2010 and 25.5M estimate for 2011 could prove conservative.”
