Including a 24k gold-plated rat-figurine is HP's marketing campaign for 2008. I can see where they can coming since their target market are small businesses, professionals and the upper income families.
HP has actually produced so many printers that I have difficulty understanding the differences between them. Nevertheless, they are really getting into specific needs of the consumer which is good.
The wireless printing kit is worth a mention too. Looks pretty but it is for specific models only I think.
