If this is related to a specific OS or company you'll need to be more specific. The only "CPI" I am aware of is "Consumer Price Index" (which doesn't sound a propos to your question) and "characters per inch" which is a typography term and could be related to imaging as well.\n\nSee the webopedia link in Sources below for definition.

http://www.consumerreports.org/cro/home.htm\n\nConsumer reports is the best resource for unbiased consumer ratings.  They get no money from companys.  \n\nI also like to look at amazons costomer reviews before i buy anything.  Just search for whatever you want and there will be tons of reviews and ratings.

Information can be organized and sorted many differnt way over many years.\nhttp://www.eia.doe.gov/\n\nhttp://tonto.eia.doe.gov/dnav/pet/hist/mg_tt_usw.htm\nIncidently, all prices are in cents.  I was confused for a minute or so until I figured that out.

That all depends on what index you use. From December 2004 to December 2005, there was a 3.4% increase in the consumer price index. Whether or not that accurately reflects cost of living, I leave to you to decide.
