Our cell phones are only a connection between my wife and I when we are at work, and the occasional contact with the kids (usually them asking if they can play the x-Box or on the computer just from another room in our tiny house, LOL.) If we are traveling, we are usually right next to each other, so really no need to have the phones. They are handy at
Walmart though because no matter how much Wifey promises she will be "right here", she is never "right here" and I end up hunting her for an hour, LOL.
The phones are just AT&T pre-paid, so they are very limited on data. They are real smart phones, but at only $10-15/month, they are extremely limited. I basically only use mine on wifi at home or work. They are not used for chit-chatting away, we don't use facebook or twitter, nor do we even use email at all. We are very private and keep to ourselves pretty much and don't really have friends that we have to stay in touch with constantly.
Since it is pre-paid, I keep it updated with 10mb data for $5/month. If I was traveling (haven't since getting the phones at Christmas time) I probably would add 500mb for $25 just so I had it if we did need it. It certainly would be useful on the road when wanting to look something up on the net.
I have a work issued laptop and I would take it along with me. I don't take it for social things, mainly it is used to dump the camera cards on every night. I would surf a few minutes at night, but not much at all. I am hourly at work, thus work is left at the timeclock when I leave the building. The laptop is for being mobile around the manufacturing plant I work at and not for keeping in contact with work when I'm not there, so I don't need to take it on travel because of work.
So, yes I would have them both, a smartphone but limited and a laptop, but they would barely be used. We only had a single Tracfone we shared when we went to Disneyworld and only had 2 Tracfones when we went to Myrtle Beach. Disneyworld the phone wasn't used at all, only there incase we needed to contact or needed contacted for an emergency by family members at home. Myrtle Beach, most of the use was my wife texting me from the balcony as I trudged out to the beach to gather up our stuff if we left it telling me "sexy man on the beach" or something silly.
