I can't think of a day that's gone by in recent memory when I have not used Google-- and when I say "use" I mean probably 5 to 10 times a day average. They've got it all: searches, maps, phone numbers, photos, videos, dictionary definitions, etc. I use "etc" because google now offers so much, I can barely keep track of it.
Thankfully, I'm not alone. The folks at TipMonkies.com put together a fantastic reference for us all: The Ultimate Guide to Google Services.
My fave new google service (which, shockingly, did not make the list) is their Pedometer service which allows you track the mileage of your runs/jogs, or in my case, brisk walks.
To keep up with google's new services in the future, check back with Google Labs.
