Interesting thoughts succinctly put, Richard. My take on this is that I want to upgrade the (borrowed) GPS I am using to one with a much larger screen.
The facilities of the Garmin 12cx are all that I need. It works well in the car and interfaces well with the laptop and AutoRoute Express. But the display is too small for old eyes (and the menu system can get away from me sometimes
)
So, what to I do? Extend your aphorism to my case and have separate PDA and GPS or go with the trend and get a combination?
What do you think?
