Ballmer says Microsoft Surface sales off to 'modest' start

Sales of Microsoft's new tablet are modest despite the fact that one model was sold out online for more than a week.

Speaking to French daily Le Parisien, Microsoft CEO Steve Ballmer said sales "are starting modestly."

Ballmer claimed that sales were constrained by the limits of the sales channel, according to the report. The Surface tablet is only available at the Microsoft Store online and, in the U.S., at a few dozen brick-and-mortar stores. But demand for the tablet through Microsoft's sales channels was apparently high enough to trigger a shortage of the $499 model online for more than a week, when it was listed as "out of stock".
