Clearly the iPad is making huge inroads in the business market. Last year Apple announced that 86 percent of Fortune 500 companies and 47 percent of Global 500 companies were testing or using the iPad. It's partly based on this growing market for the iPad that some analysts have increased their target for Apple's stock price. Also last year new survey of companies that use Microsoft Exchange servers found that Apple's iPhone has a 61 percent share among smartphones and is growing.
