Yup I concur, I have the 5500U and as noted it out performs the 6500U seemingly based on the charts here... But in all areas but the price... maybe profits, are the deciding factor! LMAO =/
They probably have something in their algorithm to always pick the newer generation if it's close, you can even see that "newer" is listed as a positive in the results. This site runs on adlinks sales revenue after all...
I don't understand this one... it seems like the 5500 won with all of the data shown. Is the statement I'm missing: "The 6500 scored less, but still"?
