Overtime big is getting smaller

It's funny how the human mind works. It simply gets used to things. When I bought my first iPhone (yes a 3GS), I thought it was big (compared to my Nokia at that time).
When I got the iPhone 4s I was really happy, the design was flawless and innovative with a hardly noticeable increase of size. I really liked that phone.

The 5S I purchased only because of the fingerprint reader, not of the size at that time. I thought it was way to big.
But now after almost a year working with the iPhone 6 looking back on the previous iPhones; they were so small ;-)
My son just got his iPhone 6s Plus. What a giant. 
I wonder when we start calling with an iPad Pro to our ears :-)
Size does matter, but overtime big things just look smaller don't they?
