Note that doing things with sudo the way Ubuntu does it is dangerous because if someone hacks into your computer (not likely if you have good security set up) or someone happens to come by your computer while sudo still keeps the password in memory, your giving full root access to said interloper. That's why you only have to type the password once for multiple sudo commands. (BTW, the timeout is adjustable) A much safer way is to use su -c foo and only issue the one command, but the quotes are needed, and that can become tiresome. But remember, it is your system and how you choose to use it is your decision. Just keep good security practices in mind and you're likely to enjoy happy computing a lot longer.

Personally I only have sudo set up to do some things, and getting a root prompt is definitely not one of them. But then again, I didn't set up sudoers to do ALL:ALL like some people do.
