The Surface will begin shipping in the US, UK, Canada, Australia, France, Germany and Hong Kong on Friday, October 26th. The Windows RT-powered Surface starts at $499 for a 32GB model, $100 cheaper than an iPad with comparable storage. The Touch Cover, one of the more interesting innovations in Microsoft's tablet venture, isn't included for that price; it's only available as part of a $599 bundle with the same 32GB tablet.
There is also a 64GB model that includes the Touch Cover for $699. Separately, the Touch Cover is $119 and the Type Cover is $129.
The Surface is available for preorder from Microsoft's website.
