FWIW I felt similarly about my Nexus 4 and was upset when it took a bath. I replaced it with a Nexus 5 and while I initially thought it might be too big, I very quickly got used to the additional size. After two years of use I like it more than the N4 in almost every way. Would a bit more storage or a slightly better camera be nice? Sure, but I almost can't imagine a feature that a new phone could add which would compel me to shell out money for it. My N5 is awesome and I hope it lasts another 2 years.
