The technical reason for power only zoom on most P&S cameras is the size of the camera, there is no space for a usable manual control. I doubt any "vast majority" of P&S users do anything but shoot at the shortest focal length most of the time except for a couple dozen shots a year while on vacation. A good percentage of forum participants might like better zoom controls but we're a tiny percentage of all users.

In short, do you think camera industry is misreading the consumer in this respect?
Define "vast majority". I'm not unnerved by it. Anyone else?

+1. Which is why I was so pleased to see the Canon S95 has a ring around the lens base that selects 28mm (equivalent), 35, 50, 85 and 105 while in auto mode. Also has the typical zoom motor control in the usual place.

which tells us, where a will is is a way or whenever the consumer demands it.
Those who are contend with a motorized slow jerky zoom have forgotten the ease of framing and shooting with a manual zoom,

Or they're people that didn't use an SLR. I'm sorry but I think a large percentage of former SLR users still interested in photography are using a DSLR so this is not an issue. I would bet the vast majority of digicam users have no SLR experience or if they did it was with some simple prime lenses. I'm sorry this is a hot topic for you personally, but I think you overstate the impact to the market as a whole.

Plus one mechanical issue, with allowing manually twistting the zoom lens while it's being driven by the motor.

You are going to damage the power transmission gear system if you twist it at the output (the external lens ring).

You gonna apply a very large torque to overcome the gear ratio.

Then there has to have some sort of "automatic clutch" to detach to lens from the gear b4 you could twist it safely, when it senses that you are apply a torque at the ouput. And that's definitely adding to the cost.

Even DSLR lenses may NOT allow automatic changeover from motor-driven to manual zoom.
