It sounds like the ipod touch may be a good choice for you. Do keep in mind, it is small about the size of a cell phone. So watching movies on it, you can but it is of course, small screen.
I live in a rural area. I do have wireless dsl as my internet service. However, when I am out, I still get internet access. It has the 'air play' OR it may be called 'airplane' .... whatever it is called, you automatically pick up the wifi service. Since you don't have the wireless service in your home, you MIGHT still be able to pick up the internet service due to that air signal. That is what a lot of people like about it. They don't have to pay extra charges and they can still get the internet service on it. But I cannot tell you for sure if it will pick up in your own home, my guess is, it probably will.
Also, that is what I was saying, many people that have an ipod touch, do not bother with a cell phone. That is because they can use the face time and skype. I also know many parents choose the ipod touch for their kids because it saves them from buying a cell phone and paying monthly fees, instead the kids can use the face time and skype.
It has calendar and all that so you can make notes/reminders.
I love the pic and video on my ipod. I use it for all my pic taking and I have done many videos with it too. It is HD quality. I have a digital camera but have not used it since buying the ipod. I guess I have had the ipod for about a year. I carry it with me every where and I have taken hundreds and hundreds of pics with it. You'll love the camera and video. There is no reason to buy a camera or video camera because the ipod touch is fantastic quality and better than my other cameras and video camera.
You can also access email such as gmail. It will display the most recent 25 messages.
