Like another poster USB is important to me, multitasking not so much (or at all, especially since I do not think any small machines do mutil-tasking). I also think flash is important, just becasue Jobs doesn't like it is not a good enough reason to not have it. While I am aware there may be some workarounds it is just bad form in my opinion. If a web site I want to use uses flash I do not want my PC, Notebook or Tablet blocking it, and I do not care who make the machine.
I just took a look at drop-box and this is not a option since I want to have access to about 500 GB worth of movies and music while traveling. USB support would give me this capability.
Besides I can wait.
