Sculley, who parted company with the Cupertino-based firm in 1993, predicted that his former employer has "many good years ahead" of it as market leader in the sector.
"The only serious tablet competitor in sight to the iPad at this time is Samsung's Galaxy," he told the Economic Times. "We know the landscape can change quickly but Apple has an extraordinary executive team.
"Companies like Sony are trying to deal with the challenges of the legacy businesses (like the money losing television unit) while Apple is riding a wave and can focus all its talent on the future."
Sculley joined Apple from Pepsi in 1983. During his tenure, he infamously licensed Apple's software to Microsoft for the development of Windows 1.0, only to take the firm to court over its successor Windows 2.0.
Apple launched its new iPad worldwide last month. The device has been tipped to sell 70 million units in 2012.
