How's the work going on the bike computer? Christmas is getting closer, the wife is asking for ideas :-)
I've been using Dakota/Oregon but also Edge, Etrex, etc. My conclusions would be :
- as capacitive is out of the question/fragile/expensive, I'm assuming we're talking resistive TS here
- resistive inheritably implies less visibility... a major complaint with Dakota/Oregon users
- and less precise controls (translated: you'd need bigger buttons to operate it using gloves)
- combine these big buttons, a required compact form factor, and the requirement for excellent visbility... and my conclusion would have to be that a touchscreen is a solution looking for a problem.
Personally, I rarely have the need to switch any screens while I'm riding, I have better things to do (...like riding). If there could possibly be any need for operating a device while riding, I'd say it would be an easy, one-button switch between data fields and map.
Any other operation would be at standstill, and there too, I fail to see much benefit of a touchscreen.
