Re: Would You purchase A 4 inch Screen iPhone 5se?
I think the SE is a great 'backup or busy day' phone. OK price for Apple, good specs, good battery (although a quick charge option would be nice). I prefer larger phone in general. I use my phone for messaging, music, reading, occasional work and for podcasts (video more than audio). I work in an office setting so having a big phone isn't generally an issue.
Although I do have both small and large tablets, I often read books on my phone, even at home. However, sometimes a big phone is more difficult (i,e. at a baseball game or a work event with lots of other things to carry). Having a phone that fits more easily into a pocket, is less obtrusive and keeps running longer is definitely a plus at times.
