They don't do it for normal books and what's the point of a lower power portable device if it requires a constant connection (but doesn't have 3G).
Firstly, I didn't think through what I said about the connecting when starting to play the audiobook. And, I have done some other experimenting. And from that I think it is just a side-effect of turning the Bluetooth on. It is possible that enabling one always enables the other so they reflect that in the UI.

It isn't necessary to have the WiFi actually connect when listening to a book. When you open a purchased book, either an ebook or an audiobook, the device does try to get the latest status in case you have been listening/reading elsewhere. But, if it can't connect, then it doesn't stop you. If WiFi is off or not available, you continue from where you were up to on that device. Actually deleting all my save WiFi services had no effect on whether the book would play or not.

Also, it would HAVE to be a very quick check. Cheap devices have BT and WiFi share a chip AND antenna. This means using both will dramatically drop WiFi speeds and possibly provide choppy BT audio. A great example was the Huawei Medipad M5. If you were using bluetooth headphones (which was kind of a must since it has no headphone jack) then you couldn't reliably stream video since the WiFi was too slow for it.

I'm guessing these devices would suffer similarly if anyone tried to do something like that. For example, playing an audiobook while using the experimental browser (do they still have this?).
Audiobooks are not played in the background. If you leave the player, it stops. So while there is a check done, it probably doesn't interfere much.

I did do a test to remove 30 or so books, started a sync to downloading them again and then started the audioplayer. I didn't hear any issues with the playback.
