Apple's integrated hardware and software system make it the most valuable personal computer maker in the world, according to a research note from Deutsche Bank.

As reported by "Silicon Alley Insider" ("http://www.businessinsider.com/chart-of-the-day-revenue-vs-operating-profit-share-of-top-pc-vendors-2010-3), Deutsche Bank assembled the revenue and operating profits of the top ten computermakers in the world. It then charted which companies are capturing the greatest share of the pie to determine which vendor is capturing the most value.

While Apple has just 7% of the share of revenue, it's grabbing 35% of the operating profit. Other companies are losing profit margins because they have to pay Microsoft for software. Deutsche Bank also notes that Apple, Dell and HP have 80% of the operating profit share on 40% of the revenue share.
