Another laptop meaning another Apple laptop or a Windows laptop? Since they two systems are very different the first thing you need to sort out is if you want an Apple or a Windows system for what you need to use it for. I will tell you for just performance, a Windows laptop for the same price will be faster. No idea what you mean "carry everywhere without being frowned upon", unless you cover your laptop with dog crap or swing it around like a mace who would be upset you are carrying a laptop of any brand?
If you like to hang around people in coffee shops that talk about which one of them visited more countries with their lawyer boyfriend or how vegan they are and complain that the latte is not being made fast enough, then you probably want to go with a MacBook. Aside from that, does not really matter and you should go by what you want the thing for and if you like spending money on bling or function.
