Microsoft launched its curious Surface Pro hybrid earlier this week, but it turns out that actually trying to buy one was a bit more problematic than people had hoped. Folks looking to get their respective hands on one of the 128GB models had it especially rough — the $999 device sold out in Microsoft’s online store and some of the company’s retail outlets, not to mention some Best Buy and Staples locations.Well, according to a tweet from Surface GM Panos Panay, the process of snagging a 128GB Surface Pro will be much easier in just a few days — he confirmed that units were on their way to Best Buy and Microsoft retail stores and that they would be ready to sell by Saturday.
