I recently purchased the Zumo and find it very easy to use. I upgraded from a GPSSMAP60c so that is the only real comparison I have. The reasons for the upgrade was more memory, expandable memory, and larger screen. Additional considerations were size, weather resistance, mounting ease, bluetooth, and the ability to operate safely on the bike. I consider the xm radio, traffic, weather, mp3 player and touch screen all 'bonuses'. The screen has been plenty bright and I haven't turned it up past half-way yet. Glare has been a non-issue as well which seemed to have plagued me on the 60c. The processing speed of the Zumo is considerably faster than the 60c and with the entire map in memory I don't have to worry about wondering outside of my maps like I would with the 60c. I am going to have an autocom installed this winter and hope this will complete my system.
You can add way points on the fly, but this is really something that you should do via software, or maybe while you are stopped along the route. The Zumo has the ability to upload information to its removable memory card, but I don't know that the NAV III has this same ability.
My only disappointment has been that when the Zumo is placed in the car mount you don't have an option to use a bluetooth headset. I would like to see an option to select which audio method you prefer. I don't know if this is a limitation when using the bike mount or not.
