Most apps that are available for ipad are also available for Android devices such as the Kindle Fire. So that's kind of a non-issue.
If money isn't a concern, you might want to consider the integration with your Apple computer and, if you have one, an iphone.
One of the reasons I went with an Android tablet (Toshiba) is that it is nicely integrated with my non-apple pc and with my Samsung android phone, so updates, say to Kindle books, email, and calendar, etc are automatically replicated to all devices. I'm pretty sure that Apple does the same thing across Apple devices.
