In his trademark style of giving away the product to audience members, Panay produced two Surface Pro tablets for onlookers before unveiling the new TV ad. Initial reports have suggested that Microsoft has sold out of the 128GB Surface Pro model, but it’s unclear how many devices were available online or at retail store across the US this weekend. Some Reddit users voiced their disappointment at retail stores receiving no stock at all, suggesting that inventory could be low.

Microsoft appears to be aware of the launch issues, noting that it’s working with retailers “to replenish supplies as quickly as possible.” The company isn’t providing exact sales numbers, much like its Surface RT launch, but it has previously indicated it will reveal numbers once Surface is more broadly distributed. A lack of retail presence and supply issues appeared to affect the original Surface RT launch over the holidays, so it’s clear Microsoft still has some work to do to ensure it can improve supply.
