I've used both iPad and Android tablets (multiple brands). I got tired of my iPad because I did not like the need for iTunes and the general "locked down" nature of the thing. I wanted to get a device that would do what I wanted without having to buy apps or "jailbreaking" to circumvent Apples likes and dislikes of what the other 90% of the World thinks is normal. Don't get me wrong, it's a great device, quality build etc but just not for me.
After messing around with multiple Android tablets (mainly cheap Chinese jobs bought while working out there) I finally caved in and bought a Samsung Galaxy Tab 2. This is the 2nd best Android tab I've used so far and IIRC, is distinguished from the Nexus by the fact it has an SD card slot so you can take it from 16Gb to 48Gb for about £12. Look at the price difference between a 16Gb and 32Gb iPad if you want to know what a big advantage that is.
I say it is the 2nd best tab I've used simply because I rather stupidly left it on a plane last week and am now the proud owner of Samsung Galaxy Tab 3 as the Tab 2 is end of life and our supplier had none left. So, I'd say have a play with both models and see if you like either. Tab 2's are pretty cheap now as stores are trying to clear them. However, as Linda says, just make sure that SWMBO has not got her heart set on an iPad because sometimes, these issues are more than just technical
Thanks for the insight and perspective especially re SD expansion which size Tab 3 did you get? As the 8 inch we saw looked a nice high res screen for a device that is still just about pocketable (at a good price point for 16GB model)??? I take your point about "iPad" naming but as it stands now it was at the time mentioned (I am sure ) more a case of that was the only tab 'name' she knew the name of
