My dumbphone is a 3 year old nokia s40 device. I wouldn't trade it for a smartphone - there is just no point. Battery life is good - at least 2 weeks on the original battery. It still works when i drop it which i do regularly. I've got an ssh client. I've got offline gmail if i want. I've made 6000 hours of calls and sent 45000 text messages. To replace it costs about 60GBP. The best thing is I'm posting from it now using Opera mini. Why would you need anything more?
