We view [R&D's uptick] as a good thing. We are investing in engineering to continue to bring out the most innovative products in the world to delight customers. We are making investments in our hardware and software engineering teams, we're shipping the best products that Apple has ever shipped today, and we've got some fabulous new products in the pipeline.

Initially, our focus was on working with the Fortune 500 and the Global 500 to get the iPad certified for their particular enterprise and I'm pleased to report that 94 percent of the Fortune 500 are testing or deploying iPads, and 75 percent of the Global 500 are testing or deploying iPads. These numbers are just off the charts for a product that's only 24 months old.

We are moving our focus away from this and focusing on penetration within these accounts. Peter alluded to some of the wins we've had in his opening comments. The incredible things about these are that they span across many verticals, through government, through education, and many different functions within the enterprise.

Yes, this means that we're applying more resources in salespeople to interact directly with these customers. We also work with our carrier partners and our reseller partners in delivering both the product and services that are wrapped around that to these customers.
