I have to point out that all the uses you mentioned for the phone involved the consumer practice of spending money in bars/restaurants, which is an inherently expensive endeavor, regardless of the "deals". Beer and burgers at home would be far less expensive. I know, social obligations sometimes necessitate exceptions, but it sounds like if you didn't have the smartphone you could've shrugged and said, "I don't know anywhere! But I have a 12 pack back at my place." ;)
Personally I've lived life just fine without a smartphone to date and have no intention of changing that any time soon. I still have a "basic" phone on my parents' plan for $10/mo. Probably not a sustainable plan in the long term but it works for now. Most of the time I feel like I could live without a cell phone at all, save perhaps for emergency use. I feel like
other people would be more miffed by my lack of one than I would be.
Anyway, isn't there still an operator who could get you numbers for places, or has that gone the way of the public phone booth?
