Just when Microsoft (NASDAQ:MSFT) looked to gain footing with its new Surface Pro 3 convertible tablet -- the first capable of replacing your laptop, Mr. Softy says -- ZDNet's Ed Bott has confirmed a problem connecting the device to high-speed wireless networks.

From what I can tell, an update to the underlying system software and firmware (i.e., code that lives and executes directly in silicon) introduced new errors to the Surface Pro 3 while fixing others. Click here to read Bott's full report.

For investors, the news comes at a bad time. Microsoft is trying to win premium customers to the Surface Pro 3 after spending most of the past two years pitching from the bargain bin:

Q1 Fiscal 2014
Q2 Fiscal 2014
Q3 Fiscal 2014

Surface Revenue

$400 million

$893 million

$494 million

Surface Cost of Revenue

$645 million

$932 million

$539 million

Yet this is also par for the course. Microsoft has spent years selling the Xbox console at a loss to gain a foothold in gaming. Then, last year, Mr. Softy pitched the Xbox One has a higher-priced alternative in hopes of winning more deep-pocketed customers. Too many went on to buy Sony's PS4, forcing Microsoft to cut prices.

Surface Pro 3 could suffer the same fate. Microsoft knows it, too, and is already offering $650 in trade-in value to anyone handing over a MacBook Air. Still, drawing such a direct comparison to Apple's sleek laptop creates risk, especially if the Surface Pro 3 fails to deliver a premium experience. That's why what looks like an otherwise small Wi-Fi bug matters so much.

What to do next? If you're a current or prospective Microsoft investor, hang tight and stay tuned here for more reporting on the error and Surface Pro 3 sales. My guess is we'll see a slowdown in the short term as the bugs get worked out. But I also like the potential -- not only for the Surface Pro 3 but also for similar convertibles as users shift computing tasks to lightweight devices.
