Ha, Apple would sue Nokia so quickly... and it'd be guaranteed to win, too. Nokia (or whoever really designed this) was pretty blatant in copying the iPad mini.
It is nowhere near clear that Apple would win against Nokia/Foxconn. If it was a patent suit it would be different, but this would not be a patent issue for appearance is governed by trademark and copyright statues and those laws have different burdens and different purposes than patent.
Patent law is more stringent for it is designed to discourage copycats to make the person who owns the patent money (and thus in theory encourage invention.) Trademark and Copyright on the other hand are designed to protect/create brand integrity. You can't make a device that is "confusingly similar" that a juror can not tell the difference between the two products. While on the surface these devices do look similar, it would be quite easy to separate them with the right marketing, with the right boxes, with the right software so it is obvious these two devices are not the same. Trademark and Copyright do not stop copycats, if they did there would be a lot less selection of things like clothes, for all you need to do is change it enough and then suddenly clothing knockoffs are legal.
I am sorry but Apple would lose this case if Nokia does it job correctly, and if you are a multimillion dollar company trust me you have enough lawyers in house to cover your ass.
Things like the back panel is all you need to survive such a lawsuit.
Image Link. Notice the big fat Nokia logo printed on the backside along with the legal jumbo. There is a reason why manufacturers do these type of silkscreens on the product even though they make the device ugly and ruin artistic balance. These steps are done to keep the lawyers happy and to prevent lawsuits.
When Nokia starts putting an apple logo on the back of their tablets, that is pretty much the soonest Apple can release the lawyers.
