Fortune reports today on a survey of 5,000 owners of wireless devices such as iPads, iPhones and Kindles by Nielsen entitled â€œThe Connected Devices Playbookâ€, which has elected to divide iPad owners into three separate groups. The first group, which makes up 63% of the total, has truly dived into the whole iPad experience with both feet, buying games and apps, reading books, shopping and so on, as seen in the above table courtesy of Nielsen. The second group, which comprises of a surprisingly very low 5%, has only ever downloaded free apps. The third group is the biggest surprise of all, being made up of 32% of iPad owners who have NEVER downloaded a single app, not even a freebie! Iâ€™m guessing these are maybe the people who like to use their iPad solely for surfing the net, watching videos on YouTube and reading their emails. Thereâ€™s certainly plenty that you can do with an iPad with the pre-installed default apps, but thatâ€™s a very high figure of users who have managed to resist the temptation of buying any apps. Not even Angry Birds!
