Well,for me,it's one iPhone 6 that I use,my old iPhone 5 that's used by my mother,an old iPhone 3G in some box somewhere,an iPad Air 2 that I use,one first gen iPad used as mouse plate for my laptops,and a 2014 MacBook Pro retina that's used daily,and the iPod nano I use as music storage in one of my cars. I also got an Apple Watch.
However,the total amount of electronics we got in our two-apartment house is: three iPhones (two in use,see above),3 iPads (two in use as iPads,one as mouse plate),5 laptops (one MacBook and one toshiba in use,the rest are old crap stored in the garage) ,three smart watches ( one apple and one garmin fenix3 in use,one first gen pebble not in use) and then there are of course a lot of other funny gadgets like cameras,gaming consoles,gps trackers (for the dogs of course) and other electronics. Yes,both people living in the house are kind of tech geeks... and I can tell,it's getting worse over time.
