Crosses at Christmas?

Now that all your Christmas decorations are up, I'm curious about a trend I've seen recently: crosses in Christmas displays.

Before Thanksgiving, I even received a press release from a company marketing Christmas crosses, all lit up for your holiday displays. But I wonder if the cross is really the appropriate symbol for Christmas.

I understand the push to keep Christ in Christmas - it's a sacred day for Christians and should be treated as such. So many other symbols are woven into the Nativity story such as the creche, or the star or even a Madonna and child. Is the cross the only symbol of Christ? And if we use the cross as a generic symbol for Christ, does it lose its power as a symbol of Christ's death and resurrection?

Any thoughts?
