In the linked article above the author talks about how Apple might buy Sony. He shows what both companies have in common. Apparently Jobs has stated that with Apples current wealth their looking "to make a strategic acquisition or two." Other possible purchases could be Disney, and Adobe. I see the later as the most likely to happen as it would be the cheapest, also it would allow apple to possibly put an end to Adobe Premiere Pro, a big competitor to Apple Final Cut Pro, both video editing softwares that hold big stakes in the market (although i hope they don't buy Adobe for fear that they might push for software to be more mac oriented instead of cross-platform(but maybe that's just me being a worrywart))
Whatever Apple decides to do, it is certain to have big reprecutions (good or bad) on the purchased business, and on Apple themselves as there would be new sources of profit for them, but alas they probably still won't lower the prices of the computers by any significant amount....oh well.
