One of the most important things you can do when it comes to listing a product on the internet is to make sure the numbers are correct. One of the most important place in a listing of a product for the numbers to be correct is in the price of the product. If the price of a product, especially one so well-covered as the XOOM, costs one price one day, then another price the next, people are going to notice. That sort of thing went down today at PC World where yesterday the price of the Motorola XOOM Wifi version cost £449.99 yesterday, and £499.99 today. Not the best thing to be revealed on the day Apple announces their new iPad to be costing the same $499 USD as it did when it didn't have a 2 listed after it.
