Actually, a little something else (Kinda like the OQO):
Make the "CPU" Module as small as possible (no battery, no keyboard, no touchpad in it) - CPU, spare mini-PCIe slot, ExpressCard, 4+ USB, Atom or whatever, 80GB HDD, 1 or 2 GB RAM, Wifi, bluetooth, maybe GPS, maybe GSM add-on module (anti-theft). That's the "machine".
Add-ons: Battery module: 3/6 cell - same size as the CPU module, stackable, can support multiple batteries; Disk drive module - stackable, DVD-RW, BluRay, you name it; Screen: 7", 9", 10", 12", with and without touchscreen - stackable to the side of the CPU, standard VGA/RCA input, so I can use the screen on other stuff also; Keyboard, touchpad, trackpoint - another stack.

So, if I only want a portable pc with no inputs, I only get the core+battery+7" LCD for navigation or watching videos or listening to my mp3s; when I get on the job, I plug in actual computer peripherals: 19" LCD, keyboard, mouse, etc. Multiple batteries will allow me to have juice for the long flights without the stuff I don't need.

If you guys want to play with this kind of software, take a look at ARToolKit: http://www.hitl.washington.edu/artoolkit/

Have you ever heard of the frogpad ?

Make it left-handed and use a simpler layout (mostly one click=one key), if you need multiple strokes for each key it's not better than a regular keyboard.

But kudos for the hard effort / innovation ! Congrats !

Lesser humans can get laid even without money, you know.

FTA:

"Nobody expected it, but yesterday SempToshiba - brazilian arm of Toshiba - presented its Media Center with a bonus: the unit has a player capable of reproducing and recording videos on Blu-ray! For those who do not remember, a few months ago, Toshiba lost the fight with Sony, the Blu-ray standard winning against HD-DVD.

Besides this curiosity, the media center sports an Intel Core 2 Duo 6300, 1.86 GHz, up to 4 GB of RAM and HD with capacity ranging from 160 GB to 750 GB. It also has Wi-Fi 802.11 b/e/g, 3 HDMI ports, 6 USB ports, VGA, DVI, S-Video and Windows Vista Home Premium."

Sorry, I thought that the system would create a link to my e-mail address automatically. My email is diogownunes2004@yahoo.com.br

I for one *am* actually designing a combined wristwatch/gsm phone/gps/OLED screen/ARM7TDMI device, though I'm not very far yet... maybe a prototype around march... Interested ? Email me.

Just add a HMD (Head Mounted Display) and software expansibility through Linux and I'm sold.
