No, I haven't heard anything like that from people. I calibrate my monitor regularly & doublecheck the images after I convert them to srgb for web use -- they seem to translate fine to other monitors. I have a crappy dell laptop that I use as my "average monitor" for comparison testing and they usually look ok there.
I think that might be a bigger issue with the wide-gamut monitors but the ACD's gamut is pretty average I think. The biggest advantage in my mind is that the backlight is very even and the colors are stable from day to day. I calibrate about once a month and any differences between the new and old profiles are tiny.
