Gold Investment present a good opportunity for 2009??

Recently, a lot of my investor raised question about investing in gold. There is no question that gold's price run up recently. But will it push permanently above $1000 per ounce? Which one should i invest, gold, stock, bond or mutual fund? It is common that investor always compare those performace against each other. Frankly speaking, i am not the gold expert. i do no have the all right answer for that. But in fact, i do some research.

Base on the historical data below, if you were invested in Gold year 1913, with the inflation adjusted, you will get a double for annual average gold price in year 2009. The best timing to invest in gold were:
1. Year 1929 to 1933 - USA Great Depression of the 1930s. People feared their bank would fail or a bank run might happen.
2. Year 1971 to 1980 - Inflation and Stagflation, where the return on bonds, equities and real estate is not adequately compensating for risk and inflation then the demand for gold increases.
3. Year 2001 to 2008 - Increasing gold demand due to USD depreciation.
