The following is a summary of the solar sun spotless day statistics, updated to January 2, 2009.

There were 266 days in 2008 without sunspots which is an indication of a significant slow down in the solar magnetic cycle. There have been three years in the last 150 years that have had more sun spotless days: 1878, 1913, and 1901.

So far the cycle transition 23/24 has accumulated 510 sunspot less days.

This is a link to Solaemon's Spotless Days Page that provides a graphical comparison of the cycle 23/24 transition to past solar cycles.
