Let me toss my thoughts out to those who are on the fence. I prefer Android over iOS (I tried an iPhone and only used it for 3 weeks) and currently have a Note 2 (VZW).
I have owned an iPad (3rd gen) which I bought for the family as well as owning a Nexus 7. I found the iPad nice for the large selection of apps, huge selection of cases, accessories, and the screen was nice. What I didn't like the lack of customization, widgets, and being tied to Apple so I went with the N7. I love being able to run pure Android, flash roms, add widgets and make the tablet look the way I want it. The fact I have an android phone means all the apps I purchased for my android phones carry over to my Nexus. I can install apps from the play store and play my music from any device.
Since I have the Note 2 now, I wanted to N10 so I just bought one and now I will be selling my N7. I am very happy I chose the Nexus 10 and can't wait to watch Netflix on that beautiful 10 inch screen !
Bottom line is both tablets are nice. Check both of them out in the stores and choose the one you think fits you best !
Hope this helps those who are undecided between the two.
NOTE: I also noticed the cost of apps on the Apple side seem more expensive. Most of the better apps are not free vs. Android has so many quality free apps. I believe in supporting developers and routinely purchase well designed apps but I have noticed more and (in my opinion) better free apps. Again, just my two cents.
