If you have a steady and secure income stream without needing a job, yeah. For those of us still depending on the job market for a while, it's not such a good thing as prolonged deflation is the surest ticket to an economic depression with no jobs.
Deflation usually doesn't mean depression (which is a mostly undefined term anyhow). There are two types, 'good' and 'bad'. Read Gary Shilling to learn more. The Great Depression gave people a skewed view of deflation.
Normally people talk about "retirees on fixed incomes" as the financially unfortunate. In a deflationary spiral, assuming their "fixed income" is from a secure source, they are the big winners economically.
True - there are other winners too. Plenty of ways to profit from deflation, if you're prepared.
