This is the forum for the 2012 version, not the 2014 wich is more powerful device and recent, and a replacer for the 2012.
Either devices will do fine, it´s just a question that the 2014 will get support for a period more extended than the 2012.
This device is great for school and students, as they can use a pen and write by hand, the screen will show the letters just like if it was on paper, they can record audio notes while writing, so that the audio note will be on the same page as the written note, I use this in my college classes and it´s great!!!!!! If necessay they can attach a mouse and a keyboard and they have something similar to a laptop (but the experience is still different), this way they can work easily on docs.
There are several versions of the device, some allow sim cards, others like mine are wifi only and so I do not need to worry about data plans, and in Europe my internet and cable company allows me to have internet connections as long as someone as Fon connection nearby.
Any more specific questions do not hesitate
