Welcome to the forum, fairysdad. I find myself selecting seats based on the laptop I'll be using - or vice versa. Indeed a first world problem!
I know what you mean about the MacBook power cable - did you know you can get a plug with a cable to plug into the power supply, as well as a plug that directly attaches and causes these clearance problems?
Wow, been a member for a while, didn't realise that was my first post!
I did know about the cables; my long one is usually permanently sited on my desk where it's snaked through by the wall so isn't that easy to grab, so I usually quickly pick up the direct plug one as it's easier to get to. If I think about it enough, I'll pick up one of the myriad random figure-8 leads I have lying around. Not a huge fan of trailing cables as a whole though, so will generally pray that the battery will last! (still got a good battery life though even though it's getting on a bit now, still better than the ten minutes you usually get with a non-Apple laptop the same sort of age!)
