The schematics posted a few days ago teased the modular port design, and the new renders now reveal that the Pocket 3 is actually a 2-in-1 laptop that includes a stylus. GPD's tweets are also suggesting that the Pocket 3 will come with Intel and AMD processor options.

Used to be a big GPD fan but after the debut of the Win 3 and all it's problems ( WiFi, QC issues , buttons not working , etc. ) not sure I'd trust another product from them unless it's fairly cheap and lets be honest GPD products are never affordable.
