Well I'm going back on what I said and not going to upgrade to the 15PM just right now...
My 3mnth old 14PM is doing a sterling job; it's immaculate/as new and does all that I need of it and seeing as I use Magsafe charging, the USB C move isn't as important to me...
I probably will upgrade in the near future; but for now, it's not the right time. More so as I'm about to spend £2k refreshing the suspension on my BMW F31... That's more important currently!
if you bought a 14PM recently, I dont think there's any real compelling reason to get a 15 PM other than 'you want to'
which is fine but probably a wise choice
