ARCHOS 101 Internet tablet

with all the tablets hitting the market recently one seems to stand out to me, Archos has allowed developers to come up with their own OS for the 101 series tablet.

Dual boot between Linux Android™ and Linux Ångström for extra freedom of use
the ARCHOS 101 internet tablet is completely open to programmers, letting you even install alternative operating systems to create your own applications and have complete control over your system environment.

I have not tried the  Ångström as of yet but I will be in the near future.
here is a picture with the input-output on the 10" tablet

Notice there is a full size USB, mini usb, mini HDMI, as well as mini SD slot.
