I have been using this for about a year and a half now and I have been preaching it to everyone. Are you at a friends house on their tablet? Works, on a phone? yep, At work in Citrix needing to make a manual? Done. it can save directly to your Google drive, it can save directly to a local PNG file you have and ofcourse as .psd. Not needing to install and being able to use it whenever makes this better then photoshop. Every time I think to myself: "I wonder if it can do X" (like pen pressure) the answer has been "yes".
