Thanks Dan,
It's interesting to note that 5 of those 13 acquisitions are for video editing software, and 1 is for DVD authoring software. It's also interesting to note that the last video editing software purchase was in 2006. Apple shopping their video division is surprising but not shocking. Apple buying Adobe seems nonsensical when looking at this list.
I misspoke about coverflow, they didn't buy the company, but bought the rights to the technology the company developed.
