The wheel will spin to a different setting just by bumping your body while hanging! As far as the switch/wheel itself failing mine has only went bezerk a time or two, and then for just brief moment, so I did not report that as a problem here.

Minolta sold something like 16 million lenses, they produced plenty of cameras with control wheels. Not to mention the fact that they made arguably the best bridge cameras on the market which also used plenty of control wheels and dials. The 7Hi, 7D & A2 were the most wheel and dialed prosumer digital cameras built at the time...Sony had plenty to go on, including being huge in consumer electronics, cameras, and video for decades themselves.
Minolta did. I don't think Konica did them any favours. those bridge cameras may have been as good as you say they were but they sure didn't set the world on fire and really thats not the topic here other than Sony put out a lot more bridge cameras than KM did. every one had at least one wheel but they also were a button to lock the selection. so you rotated the wheel to get the change you wanted (seen in the VF or on screen) then pressed the wheel to make the change. that would have been an improvement over these, that like you say make changes by accident, because you just rotate them and leave them
Sony should have known better, but I suspect they preferred to go this one on the cheap.
Probably right. the part does contain both the wheels in one piece (part numer) but theres nothing else to compare it to (no books), the A2/3/350 don't seem to have these problems. A100 is older but only has 1 wheel (and not as many sales so fewer reported problems. Henry's is the only one I've seen recently but there was a couple others) and the other 3 are newer (with higher sales numbers) with a finer wheel detent pitch and diferent feel so maybe they already fixed it?. The wheels like these were never on Sony cameras before so I think the design was inherited from KM, The ones that were on Sony bridge cameras sort of had a click feel to them but didn't really click so you could hear them and the clicks were a lot finer still like a wheel mouse wheel.
FTR and IMO the Sony top plate button positions just suck (unless you are wearing gloves, which I never am). Sony should have used a different scheme because my fingers and thumbs do not easily bend in L shapes. I never had that L problem until Sony decided to redesign proven and time tested button layouts and arrays. Sony Quicknav is cool but I prefer to make almost all of my setting adjustments on the fly through the finder..via the buttons, dials, wheels, and knobs.
I Don't have any problems with the buttons there. on other cameras there is an LCD that wastes space and I appreciate the buttons instead. and they do work well with gloves. It would have been ok with the dials the 7D had but I think I prefer the buttons like these that show in the VF when you make changes rather that too small a display that tried to show everything at once like the D90. on the 7D if you changed a dial did it show in the VF what the changes are?

See the link above where DK said the A100 has known problems with the control wheel. I have a problem with my A100 *and* A700.

The behavior of the A700 when eyestart is turned off with regards to sleep mode is strange and, I think, faulty. It causes my battery to drain much faster than it should. For example, turn eyestart off, set Info.disp.time to 5 sec, and Power save to 1 min because it will be easier to see the problems.
The first problem is that the A700 continues to use the eye sensor and that prevents the camera from going into sleep mode. While carrying the camera on the neckstrap (around your neck or over your shoulder) the eye sensor will often sense something close by and will keep the camera awake. When eyestart is turned off then the eye sensor should not be used to keep the camera awake. The eye sensor can still be used to detect that the eye is close and turn off the LCD, but after the 5 second time has elapsed *even* if something comes near the eye sensor the 1 minute sleep timer (power save) should not get reset and start over. This behaviour is okay when eyestart is turned on, but when eyestart is turned off the camera shouldn't be ruled by the eye sensor. Also, even if I hold the camera by the lens very still for 5 seconds to allow the display to go off and start the countdown to go into sleep mode I have found that outside in sunlight the eye sensor sometimes seems to be detecting something and the LCD will not go off. By the way, if someone wants to turn off eyestart but keep the LCD on for much longer then they can select a longer time for Info.disp.time and/or Power save.
The second problem is that even if the LCD goes off and 1 minute later the camera does go to sleep it is too easy for it to awaken. In order to awaken the eye sensor must detect something and the grip sensor needs to be touched. I walk around and carry my camera a lot for hours at a time (I do a lot of foreign travel photography) and because of the weight I usually have the camera strap around my neck and I am holding the camera in one hand to reduce the weight on my neck, to keep the camera from swinging around too much, and so it is instantly ready. I cannot hold the camera with my right hand because it will touch the grip sensor and the camera will awaken. I am forced to only use my left hand to hold the lens and it gets very tiresome to not be able to switch hands sometimes. Also, I have noticed that sometimes just a slight brush of my hand on the grip sensor while the camera is hanging from my neck will be enough to awaken it. With eyestart off the A700 should require a button to be pressed to awaken the camera.
By the way, the A700 designers themselves have set the precedent for ignoring the eye sensor sometimes. Another bug is that if I hold the camera to my eye and then change the ISO the LCD strangely lights up. I am looking through the viewfinder and ISO is displayed in the viewfinder. There is no reason to light up the LCD. That is a big nuisance in a dark theater or other place to have the LCD light up for no reason. The eye sensor is ignored which is strange.
I have owned and used several DSLRs from Canon, KM, and Sony. My Canon 30D did not have an eye sensor and it required a button press to awaken the camera (I usually just did a half-press of the shutter button) and it would go to sleep after the time out without any weird shenanigans like in the A700. I think that when eyestart is off the A700 should behave the same way. There have been threads about this subject on some of the digital camera discussion forums also.
I was hoping this would be fixed in the v4 firmware because it is my only major issue with the A700. Otherwise it is my favorite of 5 DSLRs I own or have owned.
