A February 15 Surface Blog post said that those ordering through the Microsoft online store in the U.S. can place an order for the 128GB model and have it ship in two to three weeks.
The new post also provided updated information for those wanting to "reserve" the Intel-based PC/tablet hybrid Surface Pro devices. Up until now, Microsoft officials have declined comment when asked whether users would be able to pre-order Surface Pros.
At Best Buy (U.S.): Inventory levels are increasing and many Best Buy stores have Surface Pro units for sale in-store. If the store does not have stock, you can reserve a Surface Pro (64GB and 128GB). Please note that Best Buy is only taking reservations in their stores for Surface Pro based on new inventory they know is coming in next week, so it's possible that reservations could become "sold out."
At Staples (U.S.): Many Staples stores have Surface Pro units for sale in stores. If the store does not have stock, you can place a kiosk order in store to purchase Surface Pro 64GB for delivery.
For Canada: In Best Buy and Future Shop stores you can reserve the 64GB Surface Pro in stores at this time. Staples has availability online while inventory lasts and more inventory has been ordered to ensure store availability in the near future. More details to come on the 128GB Surface Pro availability in Canada.
Microsoft is "work(ing) around the clock to meet that demand with production and get new inventory into retail," the post concluded. Company officials advise customers interested in the Pros to call ahead before venturing to stores this weekend, in spite of guidance earlier in the week that more stores would have stock on hand starting on Saturday, February 16.
