coffee, avira, I also did not like it when seeing other people doing it for years.
But really works for outside – self-lightning, allows for gloves without need to turn tiny pages; if it gets damaged by drops of rain, it is a broken phone, rather than a torn siddur, maybe should move the text according to where I look or even better, where the chazan is mumbling. For shabbos, probably can be automated to a certain speed like a shabbos elevator… some joke that some people wake up by shir shel yom to ask what day is it diay, but phone siddur shows the right shir. I am not really advocating phone, just found it surprising that I changed my opinion 180 when I am using it rather than others 😉 talking about bias!
