Here is my take:
Any time you can go with out steady shoot you are better off. Steady shoot can cause a stepping effect. You may not see it or you might. If it is on a tripod, you don't need it so don't use it.
Now if you switch back to SS what might happen is you may see the stepping but that is the case everytime you use it.
Hope this helps

When you say "stepping effect" are you referring to aliasing. I am curious, please elaborate.

For whatever it is worth I have never noticed any stepping effect while using stabilization on either of my VX2000s.

I'm sorry I should not have used "stepping" (with steady shoot) as the discription. I meant bouncing effect. The bouncing ball effect isn't so much an issue when zoomed wide. Care is need when you start to zoom in.
Now don't get me wrong. I much rather have that then the look of a small cam in motion but it isn't needed when using a tripod.
Now as for no Stepping Effect as Gene puts it. Well the cam isn't perfect. Look at a almost perfect vertical line and you will see some stepping because the picture is so Sharp. Now here we go again. I want that sharp look so I don't mind the slight stepping look. What I mean by stepping (incase it's different that others thought of stepping) is the busy look a vertical line will have.

Optical stabilisation does not change image performance,
electronic stabilisation does because the active CCD area is shrinked. This can cause extra "stepping", staircasing, business...effects.

The VX2000 has adjustable sharpness, so this is not a problem. One test I've done is point the camera at window blinds and adjust the sharpness...at higher levels, you see a moire pattern; at lower levels, the moire disappears. I've tried the sharpness adjustments with objects with sharp corners to try to duplicate the aliasing issues...again, at higher sharpness levels, it's visible, but not at lower levels. So no, the VX2000 isn't perfect out of the box, but you can tune it until it is.
