Apple's got incredible amounts of money in the bank, as you probably already know. According to recent financial filings, Apple is about to spend a good bit of it. The company will reportedly spend US$8 billion during the next financial year, which is more than twice what it spend during the last 12 months. A full $900 million of that will go straight to its retail stores. Last year, the company (only?) spent $614 million on retail, so that's a nice improvement.
Other areas of spending are a little bit more about company infrastructure, presumably. Apple is moving forward on that brand new "mothership" campus, and presumably no expense will be spared there. The data center down in North Carolina is also set to receive a number of updates, including a rumored "solar farm" to power it. Apple's been growing by leaps and bounds lately, and while money in the bank is always nice, it seems like this upcoming year is going to be one where the company in Cupertino invests a little bit more in itself rather than just cash.
