YES! This would be incredible. If Tana's able to add in some sort of handwriting interface with palm rejection and PDF annotation (big endeavors, IK), this app would legitimately replace most of my software subscriptions. Would easily pay $15-20 a month for something all-encompassing like this.
Totally agree! An iPad app with handwriting recognition and PDF annotation would be amazing. IMO, the value added by these features in terms of productivity would easily make up for the increased subscription price. Cheers!
