I'm not sure you save time: That round trip to the store might take an hour. Conversely, you could defer the task that needs that cable until the day after tomorrow, take 2 minutes to buy it on Amazon, and spend the next 48 hours on other stuff. To me, the hour trip to go to the store is much more burdensome than 2 minutes on my computer plus 48 hours of doing everything else that I have in my life...I run my brain on a round-robin scheduling algorithm, and there are plenty of other tasks that can keep me busy while I wait for that interrupt to return!
