Paul I use this programme occasionally for quick notes and sketches which are to easy to produce and send if you have a connected device. The big problem is the way that it saves into Drop Box and my iPad can only connect to Wi-Fi so if I am out and about and I do more than 1 sketch some are lost. I prefer Sketch Book Pro or Adobe Ideas but Paper has the best user interface of any of the ones that I have used. Most of these apps. are just down to personal preference. The Pen Tool in Adobe's Ideas does vectors but using it as a vector drawing board is nearly impossible as handles for the nodes are a devil to manipulate with the current styluses or finger.
