Apple buys a company every three to four weeks
So ~15 companies a year?  That doesn't sound outrageous for a company with billions and billions of dollars in the bank, and billions more coming in every quarter.edit: If anything there's probably immense pressure on Cook to buy buy buy more stuff.  I don't think anyone inside Apple wants to have a repeat of stuff like old Apple maps or other products that just languished and died internally while external companies innovated.  Easier to just spray the money & acquisition cannon around indiscriminately.
