Well I have a few Android Tablets and an iPad 4.
I find the Note 10.1 brilliant for all manner of things and the pressure sensitive Wacom screen with supplied stylus is great for Artwork using Sketchbook Pro & Infinate Painter. Using the same stylus with 'Multi View' where you have two Apps open at the same time and drag and drop between the two is bliss. i.e. Open your Browser of choice and Notes side by side, circle a peace of text or graphic and drag it over to the Notes App. Hand draw a shape and watch it magically transform into a perfectly drawn form or write a formula and again by magic the answer is displayed etc. etc.
The Nexus 7 is wonderful for reading books. Also, being NFC loaded makes using Tags and sharing info with other NFC devices a breeze.. Have a photo on your Galaxy SIII and want to share it with the Nexus 7? Simply load up the picture in your SIII, hold the two devices together and the file is copied across.
The Asus Transformer is very good if typing on a keyboard is your thing... It has an excellent keyboard with the added benefit of an additional battery and further ports to hook up your hardware.
Also, let us not forget Android makes heavy use of Widgets that can display all manner of information on a Home Screen be that Page 1,2,3,etc. etc.
Finally the iPad 4 which is a joy to use for both Apps I simply can not get on Andoid's Tablet list and attaching to all manner of hardware.
Basically any Tablet will suffice. They all have their strengths and weaknesses.
If there were one area I wish the iPad had that can be achieved easily with on any of the Android Tablets would be File Transfer.... Yes, you can do it on an iPad but it is nowhere near as simple and straightforward as being able to do it on an Android Tablet.
This however will not change, it is how iOS operates. Being locked down where you can't use a File Manager to construct folders for Music/Video/Photos/ etc. etc. on the iPad with no Mac/PC intervention that you can then
'share' with whatever App you have just does not happen... With files locked to an App you may also end up with multiple copies of the same file with different Apps on your iPad wasting precious space. Goodness, I even ended up copying the same video TWICE to my player of choice yesterday. It was only by accident when I noticed the Storage area of said App had a larger proportion than it should have did I then investigate and found the same video but in two places dedicated to said App. So yes, file transfer/storage I find annoying but at the same time I accept it, otherwise I would not use my lovely iPad.
