I am not sure Wi-Fi still counts as high tech.
Just kidding, it's great to have it, isn't it? Sitting on the bed with the tablet before sleep...
Anyway, don't go too happy on connecting everything, it will slow down the network. Of course, knowing that you can do it and how it would have to be dine is always nice. But in general, if you can use cable then that is the preferred method. (In my old apartment my PS3 was always connected via Wi-Fi and I am very glad to have it connected with a cable now.)
