Apple's (AAPL -1.22%) stock is hovering around $400 again, but how much has really changed for the company? Apple's still dominant in smartphones and tablets, two rapidly growing markets. Add to that $145 billion in cash and a 3% dividend yield, and Apple stock looks like a great value. 

Value and existing products aren't the only reason Fool contributor Travis Hoium thinks $400 is a deal for the stock. Some recent moves on the Apple TV may preview what's to come in the streaming business for Apple, which would surely send the stock higher. Watch the video below to see why he thinks this is a great stock to buy.
