Microsoft's trying to address the recent shortfall of Surface Pro models, and has vowed via its Surface Pro blog to get more into the market "as quickly as we can." As such, it's begun dispatching 64GB SKUs to Best Buy, Staples and its own Microsoft Store in the US, with Canada to follow in a few days. 128GB SKUs will ship "later this week" to retailers, according to Redmond, "with some units available by the end of the week." All flavors of the tablet-cum-laptop disappeared from shelves shortly after they arrived in retail stores and online, both stateside and north of the border. The company said it'll fulfill orders for customers who made a reservation first, but that your local retailer "should have (stock) soon," too.
