It was an interesting year. Thankfully the pandemic never panned out, but don't think for a second that it was not a real threat. Virtually all experts in the field will tell you that it's a matter of when, not if, we get a major flu outbreak catastrophe.
Interestingly the flu season just gone resulted in fewer deaths than usual by quite a wide margin. The working hypothesis for this is that the H1N1 flu had a competitive effect on the regular flu. So basically H1N1 supplanted the regular flu, but most older people already had immunity from earlier outbreaks. The result was fewer deaths, but the upshot is that the average age of those who did die from the flu this season was much lower.
Edit: some numbers
CDC estimates that between 43 million and 89 million cases of 2009 H1N1 occurred between April 2009 and April 10, 2010. The mid-level in this range is about 61 million people infected with 2009 H1N1.
CDC estimates that between about 195,000 and 403,000 H1N1-related hospitalizations occurred between April 2009 and April 10, 2010. The mid-level in this range is about 274,000 2009 H1N1-related hospitalizations.
CDC estimates that between about 8,870 and 18,300 2009 H1N1-related deaths occurred between April 2009 and April 10, 2010. The mid-level in this range is about 12,470 2009 H1N1-related deaths.

And before anyone gets started on the WHO "overreacting", to quote Steven Novella
Think about the alternatives – would you rather have the world governments overprepare for a pandemic that never fully manifests, or would you rather have millions of preventable deaths because those governments were shying away from possible criticism?
