It's a small USB stick that plugs into your laptop and connects to the cellphone network, at broadband speeds (the theoretical max speed is 14.4 Mb/s). In the UK, that means internet access anywhere (seriously - the networks here all have >99% population coverage, so about the only place you can't get a signal is at the top of a Scottish mountain).
You pay per amount data transferred, usually with a few GB included free if you get one on a contract. Mine's on Vodafone's old pay-as-you-go plan, so there's no monthly fee and top-ups cost me £15 (about $22) for 1GB worth of credit (and 1GB is a surprisingly large amount of data).
The stick itself works in exactly the same way as a 3G mobile phone.
They're incredibly useful if you have a laptop and travel with it, but not much use otherwise as they're more expensive than a home broadband connection. I bought mine when I was on holiday in Cornwall, and since then I tend to use it on long train journeys.
