So I've been reading about the iPad, what it does and what it doesnt do.

I have an interest in getting a tablet-pc similar to the ipad, but with the following functions (imagine I'm building ontop of the standard features of a tablet pc similar to ipad):

-Ability to pickup freeview from a freeview receiver? (or sky tv). Note, NOT through the internet, as that costs money and I'm already receiving the tv through my antenna/receiver box setup.
-Have its own OS so I can set it up how I like, have multiple apps running at the same time. Also custom free apps from many different providers (very unlike apple), multi tasking.
-Connects to my computer through WiFi and can install a remote-desktop like app on it so i can remotely access laptop from anywhere within range (within my house), to copy files across the network etc.
-Taking notes at uni: Having access to the infamous pencil app for drawing pictures, maybe a USB port so I could attach one of those floppy rubber keyboards to it for writing notes, audio recording
-Video camera, good microphone (for skype)

I think thats about it, the features the iPad doesn't have that I want. Does any of you tech-savvy guys know of a current product out, or one coming out some time in the next few months, that would satisfy most (if not all) of my needs?

Regards,
Nathan
