iPhones, iPads banned from business networks thanks to Exchange conflict
Before iOS 7 was even announced, iOS 6.1 was causing serious headaches in the enterprise IT department.
Corporate network staff warned iPhone and iPad users to avoid upgrading to the latest Apple mobile update because of a server conflict bug that would overload over Microsoft Exchange servers.
Both companies scrambled to determine what was the cause of the "excessive logging" on email servers. While Apple was left scratching its head, Microsoft came to the rescue.
The one bright side was the cooperation between the two technology giants, who not long before were at war with one another.
Samsung's breakthrough smart watch was scolded by critics
Desperate to get ahead of rumors that its archrival Apple was developing a smart watch, Samsung threw its weight behind its own Galaxy Gear.
The trouble was, it wasn't finished, and looked more akin to a slightly polished namesake device from the late 1990s.
Many dubbed it a "failure" off the mark, and still cost watch wearers $299 for the privilege of having something that wasn't complete.
Meanwhile, a number of other wearable devices hit the market later on after further development in efforts to learn from Samsung's mistakes.
Yahoo's string of fluff-ups month-on-month
Yahoo had a tough year. It spent most of its time cleaning up the horrendous mess it created by changing something, redesigning something, or upgrading a product. It left end users angry, and even its own staff stressed out.
Just months after starting at the company, Yahoo chief executive Marissa Mayer repealed the company's telecommuting policy, forcing all employees to muck-in at their respective local offices. The decision alone was controversial, but it was only compounded by a lack of explanation behind the move.
The company then gave itself a makeover with a new redesigned logo. Not one, but 30 over the course of as many days. Eventually it settled on just one, spreading the news out for longer than it should've done in efforts to milk the media's attention.
But what really angered a lot of people, including Yahoo staff who reportedly don't even eat their own "dogfood," was the redesigned Yahoo Mail, which crumbled after it first relaunched.
Thousands of users complained about the new product as a result of the bevy of technical failures and glitches.
