The major change in the next gen product is the battery (it is by far the number one request from our community). The next gen version will have an integrated battery and a dual charger which will greatly improve the user experience. There are also changes to the design and LEDs, but the major improvement for our users is battery life.
On the software side, we're continuing to make enhancements to the dashboard and app, especially as we build intelligence on top of our community database. Those changes will be rolled out to all our users, for both the first and second generation RunScribe device.
