I like the fact that I am not tied into Amazon (or Nook) for apps on the Arc. I also like that I don't have to fake a US address to be able to buy it or use it. I have no real use for it, as I have a Nexus 7, but it looks like a winner to me. I may get one for my granddaughter, who is using my old Vox. It also looks like the Arc app will have features only currently available on the Touch.
I'm getting a Glo (and maybe a Mini).
