On the smartphone side, Apple's overall advantage wasn't as pronounced: iOS smartphones represented 55 percent of activations over the quarter, compared to Android's 45 percent. The picture will no doubt change once Good starts monitoring Windows Phone activitations.
Broken down by device, the most activated device for Q1 was the iPhone 4S at 37 percent. Second in line: the iPad 2, which represented 17.7 percent of new activations. Number three was the iPhone 4 with average activation rate of 15.2 percent, followed by the iPad 3 with an activation rate of 4.3 percent among all mobile-device activations that Good monitored for the entire quarter, thought it was released just one month ago. The device had an activation rate of 12.1 percent among all devices in March alone.
In fifth and sixth place were the iPad and the iPhone 3GS, which have slowly fallen in favor among mobile workers compared to previous quarters, according to Good -- at least in terms of new activations. Given that new versions of both devices have come out this quarter, the dip isn't too surprising.
Android devices filled out the remainder of the top 10: the Motorola Droid with 1.6 percent of activations, the Samsung Galaxy S II at 1.1 percent, the Google Nexus at 0.9 percent, and the Sprint EVO 4G at 0.8 percent. The long tail of Android devices made up the remaining 16.1 percent of device activations for the quarter, according to Good.
Good also shed some light on device activation at enterprises that support dual mobile platforms versus those that support just one. "While the majority of Good's customers support a dual-OS, BYOD model, the 30 percent or so of companies that exclusively support a 'company-owned' or 'corporate liable' device model are standardizing on iOS versus Android devices," according to the report.
Finally, broken down by industry, Good found that financial service companies continued to represent the largest percentage of new device activations, with a total of 40.8 for the quarter. Business and professional services companies took second place with 9.4 percent, while the life sciences industry activated 9.3 percent. Interestingly, life sciences witnessed the highest rate of iPad activations for the quarter, according to Good, likely thanks to the fact that pharmaceutical and biotech companies in particular are increasingly embracing the devices, both for sales and for the lab environment.
