Or more, there's a psychological difference between the same dollar  
spent on fast hardware or on software to run on that fast hardware,  
particularly if the user experience is essentially identical, except  
for speed.  That is, people will more readily pay for something  
tangible.

But often, SW purchases are treated differently than HW, if not in  
terms of the accounting (i.e. depreciation of HW vs annual license  
fees for SW) than psychologically.

If I go out and spend $100K on a gofast computer, I can carry that  
100K on my balance sheet as an asset.  If I spend $100K on a SW  
license, it's not so obvious that I can carry it as an asset.  And  
let's not even get in to Section 179 or other tax credits.
