I am on my 2nd Prius (2004 then 2006). As it has been researched in the past, the break-even point of owning a Prius as opposed to a similar gasoline-only car model is somewhere around 2.5 years, but that especially includes the full tax credit, which has now been phasing out.
I love the Prius, especially the 2nd generation 2004-2009 (I did test drive the 1st generation, 2001-2003). The 3rd generation would come to the U.S. for the 2010 model (sometime in the 2009 calendar year, naturally). It has great cargo space and nice torque and battery-only use in very low mph driving & stop-n-go traffic.
I think I intend to keep the Prius until 100K miles and see if the 3rd generation is really a huge difference with the mpg because I do see a huge difference in my gas bill with my 2nd car. It's to the point that I fill up my 2nd car first (with a short work commute) before my fiancée gets to fill up the Prius (with a very long commute). That's why she's driving it for the summer, not me.
bigbet1234, with your cake business, yeah, the hatchback design really is good for opening/closing stuff into the open trunk (while I know the front of car still looks like a copy of Toyota Echo, bleh).
