I think… it still matters. Cause its the attitude in my eyes that makes all 
the difference.

When I look at this ThinkPad T520 with dual SSD BTRFS RAID 1 and dual core 
Intel Sandybridge i5 with 2,5 GHz, which can overclock itself to upto 3,2 GHz 
and compare it with that Sam440ep 667 MHz PowerPC system running AmigaOS 4.1 
from a plain 500 GB SATA harddisk, I easily get the lession about what 
efficiency truly means, especially when I notice that the AmigaOS 4.1 on that 
considerably lower spec box behaves just like it had that Intel i5 and the SSD 
RAID 1 while it does not and the KDE / Plasma system on the ThinkPad doesn´t 
feel more responsive than the AmigaOS 4.1 system, while, at the same time, the 
hardware it runs on is easily ten or more times as fast. (And sure, I know 
that the AmigaOS 4.1 setup and the Debian Sid + KDE/Plasma setup do not 
compare in term of features and functionality.)

But of course when doing for performance, its good to for the opportunities 
that give the best performance boost first. Still that doesn´t make efficient by 
default programming any less important.

And it matter related to power consumption anyway… everytime things can go in 
sleep states as they do not have to do anything, you save power. Thats 
important for any kind of portable devices. And it is also important in 
general.
