Akihabara-

I am tempted to make a shopping trip up the Tokkaido line to sniff
around for another 13-inch Macbook Pro, this time preferrably a 2015-6
era with Retina display, and upgradable to 16gb and maybe 500gb-1tb
storage. 

My 2012-era has been upgraded to 16gb/500gb Samsung 850, High Sierra,
all of which is nice, but I may pass it down and upgrade myself to a
tastier display. Not strictly necessary, but, if the price is right...

Or, anybody have a spare Macbook Air for sale? Then I sit tight, and the
"pass it down" person gets introduced to the Air... Not strictly
necessary, but, if the price is right...
