I have a truckload of tablets ...
Apple: 2x iPad 4's, 1 x iPad Mini, and 1 x iPad 2 ... gave the iPad 1 away a few weeks ago.
Samsung: 1 x Tab 10.1 (P7500), 1 x 7" Plus, and 1 x Note 10.1.
If I'm allowed to only have one from this list it will be the Note 10.1. Why? Despite it's lower res screen it is the most flexible tablet I've ever used ... i.e. can do everything anywhere with ease. No iTunes needed. Can read anything off a USB stick. Gazillions of apps (most free). The pen comes in handy when I want to annotate documents (mark stuff on documents and photos). As an engineer it is very useful to take a Google Earth snapshot and draw on that snapshot with the pen ... and then mail the picture with all my markings to others for actioning. Nothing else is as usable in so many situations. Then it also has full telephony ... i.e. it can do WhatsApp, make phone calls, and use USSD and SMS. That alone is worth its selection over Apple tablets.
My iPad's are good for photo editing (best tablet for photo work) and watching movies/mini-series etc at home. Not a devices that can truly live away from iTunes (despite iCloud and Apple trying to tell us the link has been cut). It has no open file management system so files must be loaded into apps ... and sometimes those apps don't work so well on the road ... and then you are *****ed (no opening files with another app).
So, for me, for entertainment Apple is great but for real work the Samsung Note 10.1 beats Apple into a pulp.
