You only need a carpc and a wireless lan adapter (e.g. USB or PCMCIA, find them in the shop, section Mobile equipment)
Configuration
The WLAN-adapter just has to be configured for automatic search and login into WLAN-networks. You can do this simply with a few mouse clicks. Now your carpc will recognize you when he has found a net and you instantly can access the internet for free. And there are more hotspots (locations with WLAN) than you might think...
