Hi all,
After numerous months of forum reading and patience
, I have to come to a final choice between both devices in the title.
Pros for PB : PDF columns management.
Cons for PB : SDK not yet published, software quality, delays for fixes, price (~270€)
Pros for Boox : SDK, community, quality, price (~200€)
Cons for Boox : no column management for PDF.
Pros for both versus my needs : available formats, fonts and size selection, touchscreen, wifi, note taking
What are your opinion please 
?
I won't wait until April for the nex Onyx models.
