what would be a useful accessory (addition to my MBP) to have. I just have the MBP with a Speck polycarbonate shell on it. I don't foresee any problems because I am very mindful of my little niece who is almost three who likes to get into things and pull them apart. Just one pulled off button cover that was popped back on.) I would like a cord extender. Is there such a thing? I can't move my legs easily without pulling out the magnetic part of the cord. (Not something to plug the "apple square" in, something to extend the length at top.) The cord tends to somehow weave itself around my legs, so it's not easy to move my legs around. Please don't suggest a longer extension cord... I live with my almost three year old niece and she gets into a lot of things, and so my only option is an actual mac adapter/charger. Thank you.
