Which device should I choose?
My personal favourite?
We have provided a lot of information to help you make an informed choice.
I am very reluctant to commit as this device is certainly not right for everybody. However, given the needs of many, a second-hand, full-sized iPad with an external keyboard and robust case is well-worth considering, if it meets your criteria.
I have bought many expensive cases with an integrated keyboard but they all broke very quickly.
This inexpensive brand has been my most robust case to date. More details
It isn’t perfect, but it beats having a case break every few months.
I am sure that other tablets could tick all the same boxes but I have not used them, so I am unable to comment.
