iPad Vs Galaxy, which should I get my wife?

My wife's latest Nook recently bit the dust so she's been having to read her ebooks on our laptop. We haven't had very good luck with the Nook devices, (been through 4 in the past 2 years, all due to manufacturer defects) so I'm planing on getting her a tablet for Mother's day. I've done some research and all the reviews seem to be split 50/50 on which is better Between the Galaxy and the I-Pad. So, as a tie breaker I thought I would ask the Y!A community for feed back.

This will strictly be an at home device using our home network. We won't be needing 3G or 4G. She might play some games, do some at home finance stuff, watch NetFlix, but won't be using business applications, graphic arts, or other non-entertainment apps. We don't plan on using it for pictures so the Camera feature and Retina display aren't make or break features. We also have 3 kids who are all under the age of 7, so hoping for something that can take a little abuse, they're usually good with tech and at following the rules but accidents still happen.

So, what's your opinion on the iPad vs. the Galaxy? Also, should I get the previous generation or the newest models? Let me know what you think and thanks for the input.
