Long-time Nook user with NST, GL2, GL3.
I use the GL2 as my main read, not fond of IR touch.
I'm glad to see the GL4 has Bluetooth, it must have cost them $0.50 as an option on the WiFi module.
8GB is pretty small for a $200 device. Would 16GB have blown the budget?
I wonder what processor they have. The i.MX6 Solo Lite has a long beard by now.
I wonder how much DRAM it has. I would love to see a teardown.
I use a wired clicker (into the console UART) on my GL2 to turn pages.
With Bluetooth this could be cleaner.
A handheld clicker or even footpedal might be useful.
