I've got one of the vodafone pcmcia cards, it does the same thing as a USB dongle but you can only plug them into a laptop with a pcmcia slot. They are good m8, you need to make sure your in an area where theres 3g coverage though - have a look on the website for more details... The speed is spot on, even when your downloading things, only annoything thing about mine is that its a works one and by default vodafone have content restriction in place so you can't go on any sites that are rated for over 18's etc.
Oh, if your just going to be browsing the tintermutt with it aswell you wont need a big bandwidth allowance, couple of gb a month should be ample
