The issue at hand is the return on investments, not the value of goods and services. I still purchase technology because the value of having access to that technology exceeds the current cost - the resell value. No one is buying warehouses of Galaxy Tabs, expecting for a positive return a year from now, and if normal investments (for example, the capital required to build the Galaxy Tab) which normally have a positive return assuming 2% inflation suddenly become outstripped by deflation, then no one will invest.
