I've taken thousands of shots this way and it works fine. The only way I could see it being a problem would be in a situation where the lighting was changing so rapidly that the half a second between pressing the green button and pressing the shutter button was enough time for the lighting to change too much. Pentax could fix even that by adding a custom function to make it meter again and set the shutter speed again when you press the shutter button, right before the exposure.
BTW, another poster mentioned being limited to center-weighted and spot metering. Note that M and earlier lenses always have that limitation anyway on any body, unless you modify them as Mark Roberts describes on his web site, in which case I believe you'd get matrix metering with them on the D and DS too.
