With three days to go until Microsoft’s (MSFT) Surface tablet officially launches on October 26th, WPcentral is reporting that customers have already started receiving confirmation emails that their tablets have been shipped. There hasn’t been this much anticipation for a piece of Microsoft hardware since the Xbox 360 was released in 2005. Pricing aside, consumers seem genuinely excited for the Surface as suggested by the sold out preorders. The Surface is Microsoft’s first attempt at breaking the iPad’s tablet market dominance and will be available for $499 for a 32GB model. The magnetic Touch Cover keyboard can be purchased for an extra $100.
