The good news is that you can find most anything you want with a few mouse clicks and have it show up at you front door a few days later. No more running to the store to find out that they are out of stock on that one thing you need. The bad news, is that there is nowhere to run out to on Friday afternoon when you some odd bit to get you plane ready to bring to field on Saturday morning.
I do miss having a local hobby shop to poke around in and as a place to shoot the breeze with other like minded folks, but to be honest, given the all the on-line options these days the lack of a local shop hasn't limited my ability to get whatever I need.
