Another few weeks have passed.
I have made up my mind to ditch the Jelly and go back to a bigger phone, in fact I've made up my mind to that several times. And I've also made up my mind that I cannot possibly do that.
It's difficult. One one hand many things work so well on the Jelly. I have apps, for example Google Authenticator, on a device that is unobtrusively small and is not a timewaste magnet. On the other, data entry can be a pain. Last Satuday I wanted to know whether I had time to get to a shop before it closed, and I remembered the shop's location but not its name. I found it, which makes the Jelly qualitatively different from other small phones, but the data entry was impractical compared to a large smartphone.
