Anyone regularly using the grinder bypass for pre-ground coffee in a Philips?

I have been circling the purchase of a superautomatic for months now, and at this point I have decided on the Philips 5500. However, a big point of uncertainty is the fact that we will be regularly using pre-ground coffee as my wife only drinks decaf.

Does anyone have on-going experience using pre-ground coffee in a Philips? Is there a better machine that I should be considering for this scenario? I am guessing that 60% of the time I will be using the grinder, and 40% of the time my wife will be using pre-ground...so it will not be a once in a while thing.

I appreciate any feedback on this
