The Most Important Technology for Me

I think the most important technology is cell phone.
Last summer, I went abroad, and I couldn't use my cell phone.
I worried about whether it was possible to live without cell phone
because I'd used my cell phone everyday before I went there.
But, I could to manage to spend time there without cell phone.
Though the life, I realized two points why cell phone is important.

First, we can contact with cell phone anywhere and anytime.
During my trip, I didn't need to call my friends because I was always with them.
In Japan, we aren't always together, but we sometimes want to call soon with them.

Next, we can get information around the world with cell phone
because cell phone has many function like internet.
Short trip is OK (my trip was only 9 days), but if it's long trip,
we are behind the time.
It's aniety for me.

Therefore cell phone is important.
I can't imagine this world without cell phone.
