If you own an ipad first, the likelihood of buying an android tablet or multiples to save money I would imagine to be very slim. Especially if your kid used the ipad. And I know part of that to be true in my experience.
I don't know if you've noticed but ever since 2009-2010 the same people at Macrumors have been saying only those diehard Apple fans keep buying the iOS devices, and around them there are more people switching from iOS to Android. Every year. Apple is no longer cool and everyone's buying other non-Apple phones and tablets.
Judging from the anecdotal stories offered by them here, I'd have figured everyone has now switched to another platform except a very few Apple fans, and it must be a conspiracy the sales have grown in the past few years for Apple. It's an annual ritual.
