For about over a year I have been using Adobe Ideas for quick sketches that I could import into Illustrator through the cloud. If I used the right tool the import would be in vector from the cloud while most of the other tools produced a bitmap. Well Adobe since the introduction of Ink & Slide Adobe has had to come up with some better apps for that and it has with Illustrator Draw and Illustrator Line along with Adobe Colour (mobile Kular), Adobe Shape, they can be downloaded for free. Now I like using the pad, it free's me from my desktop and using the combination of these apps made my drawings much free'er and I now quite happily can take my stuff that I drew or photographed into Illustrator as vector. Thing keep getting better.
