Are there any Amazon apps which cannot be emulated on a regular Android OS?

I know for someone like me (bigtime Amazon user and Prime member) getting a Kindle Fire should be a no-brainer. But as a dyed in the wool PC DIYer I have a problem with a device that does not offer any real expandability. I've already found out how to get the Prime streaming video service working on a different 'droid browser, but I wanted to know if there were any other key apps which absolutely do not have any alternative on a non Amazon tablet. My plan would be to see what the new Nook looks like when it gets here, and maybe look at that or the IBM A1 or something along these lines. Thanks for the help.
