John, Thank you for an informative and timely post. We are about to replace our HP laptop (similar concerns re age, etc.) and have been toying with an Air or Pro, or other Windows machine as that is what we have used extensively. We have two Garmin chartplotter said on board, as well as an iPad and two iPhones, all with Garmin BlueChart. We like the consistency of the charting. We have used Open CPN on our laptop for back up and coffee table planning, but not cruising. The laptop (whatever we get) will be backup. I assume, from your original description, that the MacBook Pro can be configured as you have the Air We are leaning to a Pro because we use the laptop as an entertainment center on board. Thoughts Thanks again.
