+Omar: I was in China for a few weeks (for some workshops and conferences in Shanghai and Shenzhen). I prioritized getting stuff I couldn't find in the US (often these are not even on Aliexpress, only on Taobao or in person). Got a few interesting Folk-related gadgets:

     * It's basically an Android tablet. Trying to root it and see what the sensor inputs are (cameras, laser line), maybe run Folk on it. It's a really nice form factor -- could also just copy it and make our own device

+    * The handheld ES228WB especially is very inspiring for a Folk gadget form factor and looks so much more modern than most barcode scanners I've seen
+    * (this makes sense, since barcode scanner is the equivalent of a cash register there -- they're very cheap, $10-20, very common, very consumer-facing)
