I spent some time exploring the BT feature and discovered a couple of things. Keyboards work as one would expect, functional for anything requiring text input, i.e. dictionary, search, etc., with results dependent upon the type and key mapping of the keyboard - same as with any tablet.
NOTE: This does not apply to notebooks/notetaking.
The real surprise was the connection of audio devices. (I thought I read audio was a going to be a no-go) The following paired and connected:
- B&O Beolit BT portable speaker
- Sennheiser Momentum TW2 and Momentum TW BT earphones (with a battery icon displayed on the Elipsa - cool!)
It connected to even more devices and also recognized a Samsung Smart TV.
So, I wonder if audiobooks will be a future option?
UPDATE: I woke up this morning with the battery at 28%. It was around 90% when I left it the night before. The only explanation is the BT, as I've not loaded tons of books just yet (10 epubs, 2 PDFs and Pocket articles) No way to confirm as there is no definitive on/off capability with the feature and there were no devices connected at the time. So, if one is inclined to experiment, be forewarned. Will continue to check for any drain and update again if needed.
