@unfa the same thing happens with ebook readers, you need to connect to a wifi and register account just to open-up the "browse books" section / skip the tutorial.
the whole thing has a bunch of analytics built-in so they can know as much stuff about you as possible, so they can try to sell you books through their built-in store.
luckily it is possible to hack the device by connecting to the PC and editing a DB file. thus never connecting to a wifi.
yes really annoying, and it is everywhere!
