Best Buy has built up a large cash reserve and remained profitable throughout its turnaround, and its financial strength opens up the possibility of share buybacks later this year. With competitors like RadioShack and Sony closing stores, Best Buy is in the position to gain further market share this year, further bolstering its financial position.

Pandora was recently forced to raise the price of its subscription service, citing higher royalty costs. This makes Pandora less attractive compared to alternatives like iTunes Radio from Apple, and Amazon's interest in music streaming is certainly bad news for the company.

J.C. Penney may have staved off bankruptcy for now, but the troubled retailer has some serious structural problems that are going to be very difficult to overcome.

Wal-Mart plans to buy used games and sell them at lower prices than the competition. This is a huge threat to GameStop, the leader in used-game sales, and it could destroy the company's biggest source of profits.

Dropbox and Box, two rival cloud storage companies, are both likely to go public sometime this year. But with intense competition from Microsoft and Google, along with Google's recent price cuts, Dropbox and Box have a very difficult road ahead.

The highly anticipated Titanfall has shipped, but server issues at launch prevented many paying customers from enjoying the game. How does this affect Microsoft's Xbox One console, and how does it affect publisher Electronic Arts?

NVIDIA's new line of notebook GPUs introduce serious gains in energy efficiency and performance, using barely more power than Intel's integrated graphics while providing playable frame rates.

SolarCity will put salespeople inside of 60 Best Buy locations, furthering Best Buy's goal of optimizing its floor space and adding to the other mini-stores already in place. This deal will benefit both companies -- here's why.

Microsoft is reportedly considering offering a free or low-cost version of Windows 8.1 in an attempt to boost the number of users, potentially threatening one of Microsoft's biggest cash cows. But the long-term benefits will likely outweigh the costs.

RadioShack had a miserable fourth quarter, and the company is quickly running out of money. With competition from Best Buy and Amazon taking its toll, RadioShack is closing more than 1,000 stores and trying to modernize the rest. But it's likely too little too late.

Massive revenue growth at CRM provider Salesforce.com is masking serious problems, and as costs rise faster than revenue, it's only a matter of time until the situation becomes unsustainable. Competition from companies like Microsoft isn't helping, and Salesforce's strategy will eventually fall apart.

Best Buy may have reported falling sales and margins, but the improvements made in 2013 and set to be made in 2014 position the company for a much brighter future.

While AMD's Mantle graphics API delivers some performance gains, Microsoft is planning to introduce similar optimizations in the next version of DirectX, and the cross-platform OpenGL is apparently already capable of the same performance gains. This leaves developers with little reason to adopt Mantle.

Staples is set to report fourth-quarter earnings on March 6, following on the heels of Office Depot's lackluster results. While the numbers may not look great, Staples' cost-cutting and growth initiatives are making progress.

Sony's PlayStation 4 is outselling Microsoft's Xbox One significantly, with a lower price driving sales. Can Microsoft's console make a comeback, or is the momentum of the PS4 too great to overcome?

While J.C. Penney's earnings report shows that the company's sales and gross margin have bottomed, returning to profitability will be a multiyear journey with no guarantee of success. Don't expect profits from J.C. Penney anytime soon.

Best Buy is set to report earnings on Feb. 27 following a disappointing holiday sales report. The company has made significant progress in becoming more competitive against online retailers like Amazon, and the earnings report should show that the turnaround effort is still on track, despite the holiday setback.

Online electronics retailer Newegg has launched an Amazon Prime-like service called Newegg Premier for just $49.99 per year. Newegg has been expanding into new categories, much like Amazon did during its early days as a book seller, and its new service might allow it to pull away customers from the online retail behemoth.

J.C. Penney is set to report quarterly earnings on Feb. 26, and the previously announced 2% increase in same-store sales, following a 30%-plus decrease in the previous year, doesn't bode well for the company. More store closings are likely, following in the footsteps of Sears and RadioShack, making a J.C. Penney turnaround looking like a long shot at best.

King Digital Entertainment, the company behind Candy Crush Saga, has filed for an IPO. With fellow social gaming company Zynga struggling to find a workable business model, and competition from upstarts as well as traditional game companies like Electronic Arts, should investors consider King?
