IMO for MBPs there is no such thing as an ‘average user’. That kinda user buys Chromebooks nowadays. It’s almost all professionals and students with different fields and usecases, and almost everyone is inconvenienced by at least one of Apple’s recent choices, be it lack of USB—A, SD, HDMI, mini-DP, magsafe, more RAM, Ethernet, upgradable components or even optical drives.

Edit: Oh and also lack of CUDA support i.e. NVIDIA cards.
