Yesterday, we reported how a pre-order page for the Motorola Xoom had gone up, then gone down again from the PC World site. Today we know why. The price was wrong.The 'real' pre-order page has now gone up and sadly, the Dixons Group, which includes PC World, Currys and Dixons, is now charging £499 for the Motorola Xoom Wi-Fi Android Honeycomb 3.0 version. So what happened over the past couple of days? Human error or bumping up the margins? We don't know, but it looks a little less attractive today, especially with an all-new iPad heading in before the month is out. Will it be cheaper elsewhere? Sadly not, the Dixons Group has an exclusive for the Wi-Fi version.According to TechRadar, Jeremy Fennell, category Director at Dixons Retail said; 'We are delighted to be able to offer our customers the chance to order this excellent product; ensuring they are first to get their hands on the product when it arrives in the UK later in the spring. Our customers will soon be able to experience the benefits it offers, including internet, gaming, email, video chat, and the ability to download all the apps that Android tablets provide.'You can find out more about the tablet from the official launch, which took place at CES. if that convinces you to purchase, you can pre-order now although no shipping date is actually mentioned on the pre-sale page.
