I would have to say the top gadgets in my house is the iPhone 3g and 3Gs. My husband has the 3G and I just got the new 3Gs and we both love them!
I use it for seriously everything!

We recently moved to a new city and do not know where anything is! I type in Food on the maps search and it brings up all the food places locally! I also just downloaded Yelp! but it seems to need more people adding reviews and what not so It can be more helpful for people like me!

The new camera is so much more awesome than I would have thought, and I love having the close up option. I also thought I would never use the video camera, and I find myself using it ALL the time. I love it!

I love my Macbook Pro, but honestly my iPhone gets way more use. I dont talk much, mostly texting and using all of the amazing apps!

I have converted several friends to the iPhone world. And they love it just as much as I do. I also love showing them new tips and tricks they didnt know how to do before. Makes me smile when I can help a friend learn something totally awesome about their phone.
