To add to the confusion, that number was as reported by Windows, which uses a binary system to calculate a gigabyte as 1,073,741,824 bytes. Over the years, however, the more common definition of gigabyte has become one billion (1,000,000,000) bytes. Using the latter, the 64GB Surface Pro has approximately 32GB free, as ZDNet blogger Ed Bott recently reported.
Shortages are not unusual in technology product launches. Apple, for example, typically quickly exhausts supplies of a new device, then takes weeks or even months to match supply with demand.
Even so, some blog and media reports seized on the quick outage of the 128GB Surface Pro as a failure on Microsoft's part, dubbing the launch "dismal" or worse.
People commenting on Panay's Saturday blog post were often even more scathing in recounting their ultimately fruitless searches for the Surface Pro, criticizing Microsoft for not having enough units, and for refusing to take orders on its website, then fulfilling them later.
Along with the Surface Pro, Microsoft is selling discounted subscriptions for Office 365 Home Premium ($80, or $20 off the regular price for a one-year subscription) as well as discounted extended warranties ($99, or $50 off), when purchased with the device.
