Not a stupid question at all. I think most people cut early because they want to peek at what's inside. It's a long 60 days, and that last week seems to be the longest.
Personally I don't cut because I like surprises and the anticipation is most of the fun.However, I will cut if I see some that haven't slit the egg themselves after the others are slit. Sometimes they have problems getting out, but I think most of the time those last ones are just lazier than the others. Better safe than sorry, though...
