As stated on the website:
Autostitch™ is the world's first fully automatic 2D image stitcher. Capable of stitching full view panoramas without any user input whatsoever, Autostitch is a breakthrough technology for panoramic photography, VR and visualisation applications. This is the first solution to stitch any panorama completely automatically, whether 1D (horizontal) or 2D (horizontal and vertical).
Autostitch is built using cutting edge research from the AI lab at UBC, but it's incredibly simple to use! Just select a set of photos, and Autostitch does the rest: digital photos in, panoramas out.
I must say when it comes to stitching the software makes the difference.
Another one is an Open Source option called hugin.

It is a bit more in depth and might require a bit more than the technically challenged want to deal with, but you can't beat the price.
