"The answer is yes (with qualifiers). Many late adopters are late adopters because they are holding out for a cheaper price for those goods. From personal experience, I've done this very thing (waiting for prices to come down on a TV before I bought it). I put that money into something with a higher return for the time being."
But you could have kept waiting and prices would have kept falling. Eventually you spent your money anyway. This seems to indicate that it wasn't the situation of falling prices that prevented you from buying a TV, since that never changed, but some external factor.
"But, the reason that's not exactly a fair comparison is that the currency itself (in this case, USD) was not deflating. Ergo, my "hoarding" was actually putting it into something with a better return for the time being, which was available because the currency was stable. If the best return I could get was holding on to my money (instead of putting it in some sort of investment vehicle), then that would be deflation."
The currency was deflating relative to TVs. Holding cash does provide a better return than holding a TV. The value of a TV depreciates much faster than cash. That's the point--why would anyone ever buy a TV when if they just held onto their money for a month they could always get a better TV for the same amount? Since TV prices are always falling, this question reduces to: why would anyone ever buy a TV? The answer is pretty simple--people want TVs. At some point if they want one, they're just going to buy one regardless of what the prices are doing, just like you did. So where's the problem?
