The biggest difference between the Nexus 7 and Nexus 10 is the form factor. If you like the bigger form factor, it will be for you. But, if you want your tablet to be almost pocketable, you will not like the Nexus 10.
That one is ok for Apple guys, I only use android, And yes I can buy and do own 8in androids, would be willing to buy an 8in nexus if the price was right.
I was just joking with you How about trying the Vizio Vtab 1008? Nice 8" screen size and 3 speakers would be awesome if it was ROMed to run Jelly Bean.
I ordered my Nexus 10 on the 13Th, should have it tomorrow or Sat. I will give you a review after I have played with it a bit. As far as the 7 goes, it was not a contender as it did not have HDMI. A shame because It looked nice. Also 216 PPI verses the 10 300 PPI resolution.
