Microsoft Surface Pro, for which people have been queuing up at many retail outlets, is tempting more people now than it was earlier. With the recent ad release the Surface Pro has started seeing a huge demand, but unfortunately for many, very less supply.

The 128 GB version of the Windows 8-powered tablet got sold out in just seven hours over Microsoft's site. The online stores of Staples and Bestbuy too show the unavailability of 128 GB version.

Fans who tried to get the device visiting the stores personally too failed in getting even after reaching before the stores opened.

"I headed down to the local Best Buy and got there 15 minutes early. I didn't expect anyone to be standing in line, but I was VERY surprised that by the time the store opened, there were 10 of us waiting for a Surface Pro. I thought, 'Wow. I didn't realize that Microsoft had even this much of a fan-base'," a member identified as Cike posted on Surface's blog site.

"We made a line in the store and I watched as the sales people unsuccessfully tried three or four different ways to order 128GB devices before throwing up their hands and saying, 'Sorry folks! We can't help you'," he added.

However, the 64 GB version of Surface Pro is available for $899 on Microsoft's online store as well as in retail stores.

Meanwhile, a new advertisement of Microsoft Surface Pro has been released, and the ad is quite appealing in terms of creativity and product details.

The main focus of the one-minute-long ad film is the newly introduced pen feature. The advertisement also shows the keyboard cover and the USB port. The dance and music of the video hint at the light weight of the device.

However, the creativity of the advertisement and the demand generated by it were marred by the supply issue for which Microsoft has always been at the receiving end.

"Customer response to the launch of Surface Pro has been amazing. We're working with our retail partners who are currently out of stock of the 128GB Surface Pro to replenish supplies as quickly as possible. Our priority is to ensure that every customer gets their new Surface Pro as soon as possible," Microsoft posted on Surface's blog.

In response to the blog post a member identified Johnny posted,
"Windows phone 8 = bloody good phone but failed distribution

Surface RT 8 = good product but failed distribution

Surface Pro 8 = good product but failed distribution

Please MS is very hard for us support you a company that is trying very hard to failed."

We hope that Microsoft resolves its supply issue as soon as possible so people who really want to get hands on this amazing devices can fulfill their dreams.
