My I-Thang and my laptop never leave my yard. I have the I-Thang because it is my phone in the US and while I'm traveling I do need to stay in touch with my office. Once on the plane in Miami the "thang" gets turned onto airplane mode and stays that way for the next three months.

I use my JA cell phone to make calls to the US as well as locally. I use my computer to check and respond to emails. If the "thang" comes out of my "home" purse - its rare. Hub uses his because I hog the computer
