I used to have an Edge 540 Solar which was not touch, and it was truly a pain to use. It felt like it was designed to be touch, then last minute added as a non-touch option. But I did like the data screen and the size. The solar charging was minimal, so when my Edge 540 was stolen I opted for the touch version without solar and I couldn't be happier! It has a good battery life, touch works so much better than the button versions, and the lack of a solar frame helps in certain light conditions as the solar frame would provide some glare once in a while. Highly recommend!
