Fools were out and about this week in an investing world jampacked with actions and ideas. Here are three articles you might find useful as you decide how to invest your money.

Why Betting on Apple or Microsoft to Win the TV Wars May Be Folly

In helping investors figure out who's going to win control of the living room, Fool analyst Tim Beyers points out that: "The most successful tech products of the past 20 years have been feature-limited and partnership-poor by design. They were instead created to do something extremely simple with surprising efficiency."

Tim turns his gaze away from Microsoft (Nasdaq: MSFT), Netflix (Nasdaq: NFLX), and Apple (Nasdaq: AAPL) and toward Google and its rumored plan to become a cable alternative. "Only Google proposes to own the pipe in the same way that the current remote suppliers -- the cable and satellite operators -- do," wrote Tim. "It's a devastatingly disruptive opportunity for just how neatly it fits into how we already watch TV."

High Oil Prices Are Here to Stay

Fool analyst Dan Dzombak took a look at some numbers indicating why high oil prices aren't going away. Information from Carnegie Investment Bank shows a range of oil prices that exporting countries need to support their governments. Dan's chart ranges from $80 per barrel for Saudi Arabia to $110 for Russia.

"This is a massive incentive for these countries to work to keep world oil prices high," wrote Dan.

Unconventional oil sources such as shale and tar sands will play a small role in growing oil production (at a higher cost than traditional sources), said Dan, while OPEC expects the biggest production gains to come from Brazil's deepwater fields and Iraq.

"A good way to protect yourself from rising oil prices is to invest in oil, so you make money as prices rise," concludes Dan. Read the article to see what Dan has to say about opportunities at ConocoPhillips (NYSE: COP), SandRidge Energy, and ATP Oil and Gas.

Amazon Is Tier 1

Motley Fool Rising Star analyst Joe Tenebruso seeks out "elite businesses" for his Tier 1 Investments portfolio. "These include companies with the most valuable brands, best management, superior products and services, and strongest competitive advantages," writes Joe.

Amazon.com (Nasdaq: AMZN) was on Joe's radar this week. One of the things he focuses on is how Amazon is expanding its moat through its Amazon Prime program, which offers free two-day shipping and free Internet video streaming to those who pay the $79 annual fee. "The Kindle Fire should only help to expand the value of Prime, and in turn the value proposition of shopping through Amazon," writes Joe.
