Take On the Giant
Samsung isn't exactly a David, but it challenged Goliath Apple when it launched the Galaxy Tab, the first real rival to the iPad. (Apple did more than just take note: It is suing, and Samsung is countersuing, over alleged copyright infringement.) In this first battle of the tablet wars, the Galaxy Tab came out fighting, whacking iPad's market share from 93% to 73% and instantly claiming 17% of the market, according to IDC. The new Galaxy Tab 10.1 is now up against the similarly priced iPad 2 and others, and the battle rages on.
