Inflation only goes one way because deflation isn't really good. It creates a situation where not spending money nets a return. Inflation means you need to spend or you lose value. The ideal is wages keep up with inflation (which they aren't).
Now, I don't really buy into the Keynesian economics idea like I used to, that forcing spending is a good thing for the economy. Yeah, it boosts economic activity, but does that net really help the average person or only the elites? However, I still think deflation, especially to any significant degree, is almost certainly bad. It would cripple economic activity, which would cost jobs, because the best thing you could do is spend as little as possible.
However, computer hardware prices aren't really inflation. They effect the measure of inflation, but they aren't caused by it. They're caused by incredible demand, and a lack of supply. There's some inflationary effect to it, but their price has increased far faster than the price of their inputs.
