Greg is locked into using an old phone because his skin is too dry to use a touch screen. Is there a smartphone that has raised keys anymore? Leo says Greg could use a standard Bluetooth keyboard with any smartphone and that would solve a lot of his problem. Leo recommends the Aerb wireless keyboard at Amazon. It has a trackpad with it, and is only the size of a game controller. The RII i28 is another one.
Logitech has the K480, which has a stand for his phone as well.
