Just curious as to why you think touchscreen is not a goof idea? I think in a few years that may be the only option as all electronic devices seem to be phasing out buttons and knobs. They work pretty darn well on iphones...I'll be getting a new system but it won't be a touch screen, I can't imagine that being a good idea. My idea is a Garmin 820xs or 840xs with down scan and side scan. I was originally thinking at 700 series but the touch screen turned me off.
