So, some of the pieces are difficult to impossible if not expensive to 
get in singles.

What your suggesting is perfectly do able, but is likely a several 
thousand dollar project and involves a lot of different technical 
skills. Ordering parts more directly through digikey or mouser will 
certainly help keep costs down. Expect to break or blow-up components 
while learning.

If you want to get to know some folks that do this for hobby or 
professional, I'd suggest finding your local hacker/maker space.


Let's go through your list assuming hobbyist sources.

*nav(compass,gps or Europe satellite position system?, etc)




*2 stereo line-out/headphones
*6 (hehe wishful thinking i hope not :P) line-ins (6x1channel)

Not sure, look at the PIC microcontroller range. My colleague that does 
audio and synthesizers uses them for his products.

*hd webcam no mpeg-al -no h264, mpeg4, etc-


*LED light for webcam and/or inferred led(s)


*butitin mic

*several hour or all day battery life :P

Oh boy... now your taking laptop battery and real heft.

*keyboard (could be a stand-a-lone mini wireless one from china that 
attaches to what would be a mini tablet thing) (can you get a mini 
wireless human input device that has a usb cabe connection option? save 
battery juice by not using wireless.)

I absouletly love these. Have two at home, one at work (great in the 
data centre) and another gifted to by boyfriend for his media centre.


*30M fm transmitter

Amazing how you can abuse I/O pins.

*RF radio? walkie-talkie


*peazio sounder

Cheap, readily avaliable from sparkfun, adafruit, digikey, mouser, 
Element 14, RS, etc..

*gpio or something arduind like or serial like?

Some on the EMOA-68, others form any micro-controller you use.

*long range remote (garage door, 500M) -anti thief?

Not sure.

*vibrator -for alarms!-


*touch screen


*screen lcd, colour e-ink, led ? Must be usable/piratical in full
