"I've been using the Mac solely for years, and got very comfortable with it"

Jerry Goldsmith's quote recommends that he has actually been utilizing the Mac computer for a long period of time and has become extremely knowledgeable about it. This implies that he has become accustomed to the Mac's functions and abilities, and is comfortable with the way it works. It is likely that he has been utilizing the Mac for a number of years, as he states that he has been using it "exclusively" for several years. This recommends that he has not used any other kind of computer system during this time, and has become extremely comfy with the Mac. This might be due to the truth that he has actually become familiar with the Mac's user interface, and has the ability to use it efficiently and successfully. It is most likely that he has actually become so comfortable with the Mac that he has the ability to utilize it with no problem.
