Earlier this summer, Cisco (Nasdaq: CSCO) announced plans to enter the tablet game with a business-focused product. Some in the business world painted the entry as an "Apple-crushing" move, but Fool co-founder David Gardner wants to eschew that line of thinking.

Investing is not like a sporting event, even though we're led to believe it's an X-vs.-Y game -- AOL versus Microsoft back in the day, or Apple's (Nasdaq: AAPL) iPad versus Amazon's (Nasdaq: AMZN) Kindle now.

In this Fool TV video, David explains why more often than not, there aren't zero-sum stakes. He believes Amazon and Apple both make great products -- and that both can reward shareholders. And if Cisco can make the Cius a great product, it too can succeed for Cisco shareholders. Watch the video here:
