Autodesk Student Version-Free for Students and Teachers

[cmpm]

Autodesk Student Version, puts watermark on print output, but a good deal for some expensive software. If you have room on your drive, these dudes are quite big!

Looks like a very good deal, especially as they do not ask for school references.

Nice resource. It's also available to veterans of related fields or to unemployed individuals.

 Wish this was around when I was in school!  I don't have a need for this type of thing anymore.  Still, big thumbs up to whoever finally approved of and implemented this for those who can use it.

Just downloaded Sketchbook Designer 2012 - looks like a very nice app.

Whilst the application prints with a watermark it will also export to Photoshop PSD format without the watermark - so it really isn't a huge limitation!
