Dell Inc., the world's No.2 PC maker, expects to launch a significant number of tablet PC models next year, its chief executive said on Tuesday, drawing the product's growing popularity since the launch of Apple Inc's iPad.

Speaking at an event in Hong Kong, Michael Dell added that it was easier to develop smart phones on a platform using Microsoft's Windows operating system than using Google's popular free Android system.

Dell also said the company would make an announcement later on Tuesday related to cloud computing.
