I have a playbook - there is so much to like about it, in particular that it runs QNX and with a terminal emulator (I'd have to look up the name) you have a very cool terminal based tablet, even including it's own elVIs VI editor and python 3.5.
The problem for me though is networking. I fired it up a couple of years ago and found that very few urls will work with either the browser or with curl/wget/urllib which I am more interested in. I couldn't find any information about this, so I don't know if it was a https or certificate issue somehow, or if something in mine is broken. If you saw anything similar, it would be great to know if/how you resolved it.
