I am reviewing this new Autopano giga 2.0 software.  This image was created from the 5 images below.  This software has a neat feature that color corrects the images.  The auto stitch feature works great.  I compared this to the auto stitch in photoshop.  Autopano took 8 seconds to render a visual sample of these 5 images and rendered the final image into a 31 megapixel pano in 3.5 minutes.  Wow that was fast.   The test images were done on a Intel based 2.4 ghz processor with 4 gigs of ram.
