Drive space is overrated

I welcome SSDs - not only because they are quiet, but also because they consume less power.

What is the logic behind computers? Is

1. faster is better,
2. more space is better
3. cooler is better ?

What most people like to have on a hard drive : 
Office Suite
Specialized program ( AutoCAD, AvidExpress, Photoshop/GIMP, Nvivo,  Cakewalk/Sonar, etc.)
Skype
and a few others.

Really most of this will almost always fit well in 32-64GB hard drive.

I hate wasting my time managing drive space, but now external hard drives are so cheap, that the "storage" function can be altogether eliminated from the main part of the computer.
