Alone, Apple is Worth As Much as Microsoft, HP, and Dell Combined

Right now Apple's market value is about $302.4 Billion, and HP's market value is $72.8 Billion, Microsoft is $200.3 Billion, and Dell $29.3, so if you did the math you'll find out that Apple's market value is actually more than all these companies values all together.
The different between Microsoft's market value and Apple's market value is about $100 Billion, and i think one of the reasons Apple is one step over Microsoft is because of iPhone 4 and iPad 2, because Microsoft's Windows phone is actually no match for iPhone 4. Microsoft's Windows phone came too late after iPhone 4, and also Microsoft doesn't have a hug app store like Apple's app store ( and they'll never have one ).
