Of all the technology or inventions in your life, which is the best? Most useful? The one you can't live without?

There have been a lot of technological advances in the last few years (I even wrote about them here and here (plus I made this video). Some of the best inventions have come and gone quickly, but many have stood the test of time and are still in use.

According to a recent study Broadband (Internet) tops the list and then the washing machine follows! Rounding out the top 7 are email, fridge, freezer, and microwave.

Yes. Those polled believe that the internet is more important than the microwave, contact lenses, and even air conditioning (that made the list at number 28 just behind digital radio). Are these people crazy or am I just the odd man out on this one? Let me know what your must have invention is in the comments below.
