Apple's iPad has had remarkable success in the corporate world, but a new survey has shown that adoption of the tablet has been driven by demand from the bottom-up rather than the top-down, leaving many companies unable to articulate a strategy for using them, CNet reports. Dimensional Research did a survey of 448 businesses, and found that half could not clearly explain what they plan to do with them. Nonetheless, the survey showed that the iPad is the overwhelming choice of businesses, even in the face of current and forthcoming more business-oriented tablets.
