We still don't have service at the house, but it is amazing what can be done with a wifi connection. And when we are traveling the phones act as mini-computers. It is so great. And he actually remembers to carry his phone now so it is easier for me to get in touch with him when I need to.
The only problem I have - my cell phone is already "out-dated" and I want the newest version. Maybe I can convince my DH to upgrade soon.
