A cure would be good news for type-1s- this I'm as sceptical about as I am about "modern" synthetic insulins.
For the majority of type-1s injections are not painful, and if it is occasionally so what, it's no more painful than bashing my leg with my bike padal. it's just something you get used to. Of course for children, daily injections can be painful and upsetting, so perhaps a pill form would be helpful for younger type-1s. Personally I'd favour injections over tablets any day, but I hate taking tablets, always had a bit of a phobia. Love needles though!
I'd still rather the money being spent to develop these insulin delivery systems,like the failed inhalers, were put into research to find a cure.
