What is it I need? Portable computer?

I need a kind of mini computer I THINK. I saw this one project where this guy had a small lcd screen and his webcam from his pc was displaying his camera/movie on the LCD display... What do you recommend? I need a mini computer like device that can make HTTP post requests so basically it has wifi and it can compute its location by perhaps connecting to a GPS...

2 things I need but I dont know what kind of device will do the job cheapest...

1, it can make http requests so basically POST to a url

2, it can track or know the cooridnates or location of the device using some kind of GPS perhaps?

I know I am being very vague but I don't even know how to get started on getting the things I need. I am just very scattered.

Is this project on the Internet somewhere so we can look at it? If not you will probably have to be more specific about why displaying video on a small LCD needs location information. Is the camera moving or is the display moving or both?!?

I need a small LCD that can make HTTP posts to a url AND record its location in coordinates for example using gps maybe? the LCD is moving there is no webcam that was just an example.

So at a minimum you want a GPS with mass storage for logging and Internet access. And a "small" LCD.

Is the LCD actually used for anything? You have not said what the LCD is used for.

What size do you consider "small" for an LCD?

Will there be WiFi available everywhere the LCD is moving or will you need something with greater coverage such a GSM/Cellular.

twirap: I need a small LCD that can make HTTP posts to a url AND record its location in coordinates for example using gps maybe? the LCD is moving there is no webcam that was just an example.

So an arduino with GPS sensor and wifi connection to an HTTP server and a display shield? You can get them here:
