Though the odds are against it and pricing seems questionable to some, launch-day preorders for the base model of Microsoft’s (MSFT) debut tablet are already sold out. As of Wednesday morning, less than 24 hours after pre-sales went live at noon on Wednesday, shipping times for the stand-alone 32GB Microsoft Surface tablet slipped to “within 3 weeks.” Microsoft did state on Tuesday that preorder inventory would be limited, though it did not clarify how many tablets it would have on hand for pre-sales. As of the time of this writing, launch-day inventory of the 32GB Surface with a black Touch Cover ($599) and the 64GB Surface with a black Touch Cover ($699) was still available. BGR on Tuesday published an in-depth look at the three-year process that lead to the Surface tablet, and said it was a device that marks the start of a major strategic transition at Microsoft. The Surface launches at midnight on October 26th starting at $499.
