It's really unusual in this day and age that someone would not have a 'smart phone' which is a phone that has a qwerty keyboard. Not only do they have internet and faster texting but they have a perk for writers.
Everyone always says a writer should always have a notebook and pen on them. Well on smart phones you have a built in notepad that you can just pull out your phone and type in what you want to remember or what inspired you. That way you don't have anything extra to carry, just your phone. You don't need a blackberry or an iPhone, any smart phone will work. My notepad has come in handy when I needed to write things down, it could for you too. Look into it!
