apparently this post which would have been on the first page is still sat in an open windows and got stuck at the new post stage. but here was my first advice since I've already typed it.
---------
If you're in the Apple world, grab and Air2 and be done with it.
they are nice tablets but not for me.
But for you with you iPhone you'll be able to transfer purchases etc I would hope.
For me it would either be the emerging Windows tablet at the 90 to 120 quid mark.
they are great.
Or the Hudl2 or something similar. Unfortunately the nexus series priced itself out with the Nexus9 as Nexus normally sold due to being excellent and cheap-ish Also 9 inch is too big for lugging around (7 was perfect and so would modern 8's in the same size package. But it is the direct Air2 competitor if that format is fine for you-
-----------
Hudl2 and SD cards.
No it's perfectly fine for what you want to do, but it cannot be used for expansion of internal storage for main programs things they download themselves like they 'marking' lead you to believe. At least not yet! (it was once upon a time was able to way back some years ago.)
BUT for your needs it'll not be a prablem.
Buy a card like a 32 or 64GB EVO microSD card with adaptor of Amazon and it may well be faster than your current card (I don't know but these are pretty fast compared to my older SD cards).
Being in an adaptor means you can then take the microSD card out and put it in the tablet. I think, but check, that it's easy to access.
If you have a big Tesco near you go have a look, they'll have samsung and other including the Air2 probably.
Nothing wrong with Samsung as such, they make decent stuff. I just don't like the User Interface they stick on top of the normal Android interface.. All my devices use the almost default current interface. (Moto G phone, Toshiba Excite Pro, Nexus 7 and in fact my aging 4 year old shouldn't be running it Orange San Francisco phone uses it too if you know how to put newer OS's on them).
apparently having a read around, battery is 6hrs ish on full charge watching video constantly, so it's plug it in overnight job, but I do that as habit and tend to plug in if near one of the chargers anyway. So wouldn't be a problem.
Also the Tesco side swiping thing can be a be stuttery, you'll not use it unless you are a Tesco shopper so change to Google Launcher once you've worked out how to do it, that apparently doesn't have the problem.
I'll surf (in whatever browser you care for, not seen safari though)
It'll read email (in whatever program you care for, GMail now picks up most others easily, not sure about Apple mail things)
It'll play video, musics, movies (not sure about stuff from Apple Store/Tunes thing.
It'll read your pics and you can use any app to play with them and alter them. I'd recommend Installing Google Drive/Google+ and having it auto back up (or one of the other auto backups doing it)
Depends what you use.
SD card and adaptor, I now use these in my camera's
32Evo with adaptor
fast enough for me, price changes all the time and drops to 11 or 12.

I always buy from the Amazon supplied for SD cards as there are so many dodgy ones cropping up.
