Over three quarters of corporate buyers planning to buy tablets in early 2011 still plan to get iPads, ChangeWave said in a new study. About 78 percent of those committed to tablets in the first three months of next year were intent on getting an iPad. Although RIM saw an improvement as it edged closer to release, only nine percent expected to get its BlackBerry PlayBook, which was now tied with Dell tablets like the Streak and the upcoming seven-inch Looking Glass.
