The Nokia 770 is a huge deal for all the Linux PDA fans outside of Japan. For the first time since the Zaurus 6000 was discontinued, we have a production Linux PDA widely available (at your local CompUSA even). Hopefully Nokia will support their developers better than Sharp has, and bring additional devices to market in the future.
I've made a feature comparison chart between the Nokia 770 and Sharp C-760 here:http://www.markandjo.com/markblog/?p=86
I've also included several side-by-side pictures to attempt to show the differences in form factor and screens. Links to the pictures are just below the chart.
Please let me know if there are any other pictures you would like to see, and I'll try to take some more.
