When Microsoft Corp. (NASDAQ: MSFT) released its Windows Vista operating system product almost two years ago, the market was initially excited. That excitement turned to boring indifference as customers, both business and consumer, realized that this was just another update to Windows. Nothing revolutionary, or even evolutionary (in many minds). The problem was this: Windows Vista was a huge change under the hood, but where its users interact with it, it seems like a boring reinvention of an operating system from half a decade ago.

But Microsoft doesn't just make operating systems. It's into the office productivity business (Microsoft Office, anyone), it's big into the mobile business (Windows Mobile), and it's tried desperately to compete with Google Inc. (NASDAQ: GOOG) in the web search advertising business (which has largely failed). So, the company, which continues to make a ton of cash every quarter by selling Windows on all those global PCs that are sold, has no debt and a ton of cash under the mattress. It's still a boring company with a business model that's being made rapidly outdated by the internet and web-based competitors. Should it take its cash, return it to shareholders, and close up shop? Though this was suggested of Apple Inc. (NASDAQ: AAPL) some time back, that company roared back (maybe you've heard). Can Microsoft?
