New SketchBookMobile: 1.1 a-go-go
As ever, it looks like Josh beat us to the jump with this one, but its worth covering a little. Autodesk just pushed out the 1.1 release of SketchBookMobile and it addresses some of the issues with the initial release, namely, layer perservation (you can now push out a .PSD file out to Photoshop) and for me, the big one, importing landscape image (which is something I'd asked about when it launched) and brush preview when you're resizing them. It's available now on the App store. Josh also has a very handy comparison chart looking at other sketching apps for the iPhone.
Finally, here's a slick little vid* that shows a workflow with moving data from concept to 3D with SketchBookMobile and Inventor.
* nice video, but honestly. Where the hell are they getting this music from?
