Smartphones are Orwellian and stupid imo. Unless a smartphone is released running something BSD-based and open source, then I'm happy with an ol' fashioned number-pad phone. These hyper-powerful PC-replacement type phones are all huge unwieldy things that I don't want to be carrying around in my pocket.
I have to admit that I had the exact same thoughts as you.
Ever since I got the S4, I've realized how easy it is.
Lost in a city? no worries, google maps got you covered.
Got to reply to a quick e-mail? no worries various e-mail apps/internet browser can do it.
Important conversations, messages etc.
Hell, if you got kids and they made something precious or are playing in such a way you'd want to snap a picture, grab your phone.
Can instantaneously share it with the wife/friends as well.
As for open source, you can flash a custom ROM to a phone.
Camera quality might degrade and some features might not work but eh, the majority of the thing works.
I'm not trying to be a smartphone advocate or forcing you to get one but it is a hell of a lot better then having an old number-pad brick or flip-phone.
But yeh, I do agree on the phablets, way to fucking big.
