Perhaps I'm misreading the OP's requirements when they ask for "music, watching movies and browsing" but all three tablets are capable of doing just that.
If the OP does want the best in resale value, sure, go for the iPad but I've not seen any indication that that is a primary factor in their usage (being music, watching movies and browsing).
Overall though I was just throwing a new (budget concious) suggestion in that can do all the OP asked for which they may have not considered prior to this thread.. The thing even looks like it'll be laright for a little light gaming too. http://www.youtube.com/watch?v=uPXOJC1qm6o
Sure - I get it. My initial recommendation for the iPad mini were for the top two reasons the OP mentioned - music and browsing. The 4:3 aspect ratio is superior for browsing - not to mention the added screen real estate.
I too mentioned that if the OP were budget conscious, the N7 would work just fine and is a nice tablet for the price.
And I wasn't knocking you for throwing in a new consideration - merely cautioning that in my experience, you get what you pay for

If your gonna make a comment on the tablet at least know what your talking about. Pretty much every android tablet including both nexuses is 16x10 not 16x9. The app argument is not valid either. There are just as many apps on android as on iOS.
The screen on the nexus 7 is noticeably better, especially text. It also better for movies as the aspect ratio is better. Theres also the fact that unlike the mini (wifi) it has a built in gps chip. The wifi minis have no gps.
Lol - 16:9, 16:10 - both are inferior for web browsing. And the screen size of the mini allows for a better browsing experience as well.
And sure, there are 700,000 apps in both stores - how many of those Android apps are written specifically for tablets? i.e. make better use of the added screen real estate with extra functionality - or how about even optimized for the tablet's resolution? The answer is not many - and this is from experience with the Nexus 7.
Conversely there are over 300,000 iPad-specific apps with added functionality and optimization specifically for the iPad. The OP originally listed 3 uses - movies, music and browsing. For at least two of those I would say the mini is superior - for movies, the 16:10 ratio is better sure, but since selling my retina iPad, I've been watching more video on my mini, and I have to say I'm very impressed....
And this is coming from a retina iPad - so don't talk to me about the Nexus 7 screen being noticeably better.....its not all about resolution and PPI....app optimization, color gamut and the display's manufacturing process all play a role - hence why the iPhone 5 screen is much better than even the iPhone 4S screen - with exactly the same PPI and relative resolution....
