I did one for my little boy and the look on his face was absolutely priceless! He got a special email from Santa with a link to the Portable North Pole "TV" and Santa greets him by name , says his name several times over the course of the video and I get to personalize it with photos and tidbits of info that only Santa would know because he is watching every move he makes. Okay, that last part sounds super creepy but it is so cool none the less.
The only draw back I for see is when my baby girl is older... her name is traditionally a boys name and is not on the list because it is not very popular (my sister called it ethnic aka very Irish) but eh... a popular baby mags predicts that it will be a top 10 boy name in 2012 hehehe.
