I haven't been keeping up with the rumors so curious if you knew... if the outer screen usable with the pen??
Honestly, I don't see the practicality of the pen if it's only inside...
With the Note series even though large you can hold the phone with one hand in palm like you would a note pad and then write if needed.
But I'm thinking with the Fold, you have to open it up and hold it by the bottom (??) as if holding a small open book (if you don't have it on a flat surface to write on) so that you can hold the pen on the other hand to write... jotting a quick note or taking a few notes, etc., while on the move. Who wants to do that??
But if the outer glass screen is writable then we're good.
*Edit... And then there is the thought where am I gonna put the pen while I carry the Fold in my front pocket if I were to get one and want to utilize the pen. Because for a mobile phone, I pocket carry 100%. No other way. It's like my iPads... all pen capable... but I don't have a single pen cause I don't want to deal with carrying it even in my backpack.
