16" feels quite uncommon. We tend to hear people using 15", then usually jump to 17".That is why they keep PS3.....lol
Anyway, to them Max performance market is actually for larger sizes. Like PS2 time they had 17" above only where GY GS-D3 had 15". Then when Asy started they phase out 15" but PS3 came out with it, however now we know PS3 is not PS2 replacement that is why they have 15".
When PSS came out it is 18" above like CSC6 now...
For PS4 lucky for some 16" kaki.....hhahhaha
