I have both an iPad 4 and a Note 10.1
The Note 10.1 feels so much nicer to hold ~ it's lighter and doesn't hurt the palm of your hands, unlike the iPad 4 ~ always cold to the touch, heavy and is horrendous at leaving a pain at the base of my thumbs when held for anything over a few minutes.
Next up try and import a file onto the iPad..... It's a bloody nightmare, where you have to rely on either iTunes or a convoluted and idiotic file transfer in using the likes of cloud based services and even then you are severely limited.....
There's no file management per se. You can't simply drop a photo, video, music, or whatever into a chosen directory as there is no such thing in iOS.
Instead you have to associate a file to an App and even then you can't see or share that App with another App.
Photos if imported using the Camera Connection Kit have to have a specific file name structure.... It has to be Eight characters long... no longer and no less otherwise you can not transfer a photo or video across to the iPad.
Bluetooth file transfer is a complete and total No No.... Again iOS does not allow Bluetooth to communicate from one machine to another machine to transfer a file as it is deemed a security issue.... Oh come on Apple.
I could go on and on about the pitfalls of the iPad such as no true multitasking showing multiple programs at the same time, no widgets on the home screen, no way to organize the home screen icons in any way other than drag and drop or a basic folder structure, no real notification apps, etc. etc..... but suffice to say it does have it's benefits.....
Where the iPad shines best is the amount of software available..... This is where Android and Samsung are letting down their Tablet devices. Until Google come up with a down and out plan to introduce more and better titles the iPad is always going to sell in higher numbers.
