I have had the Droid X and my wife has had the incredible for about a week. Both are great phones. The incredible is very compact and can do much of what the X can do. The X is bigger, but the features and apps are awesome. The incredible does take good pictures. I don't have any issues with the X, but I just usually use the phone to upload pics to facebook or MMS to family members. If I want print quality, I will use a camera. Nevertheless, I have not tried to print any yet. It is 8mp's. My wife is actually getting a new increidible today. She loves it, but the phone keeps turning off when she tries to answer it or make a call. We are convinced it is just a bad phone and not indicative of the line.
So, if you want a compact phone, go with the incredible, if you want a bigger phone, with bigger LCD and more features, go with the X.
