The smartphone market´s desire to make everything superthin kind of reminds me of the old phones and making everything so tiny:

And them Smarthphone came to help us..

Problem is we have gone from Cement Block phones to microphones (no pun intended) to Tile phones... it seems like they really need to show they are capable of shrinking things.

The reason I stated the headphone jack removal is because I wanted to show how obsessed Apple is with thin products.

I don't use headphones(rarely), so i don't even care for that. i just hate how they're just aiming for everything to be skinny. It's to the point where it's uncomfortable

Other phones and notebooks also get thinner. Why do we have this discussion every single year? When the iPhone 5 released people said the same thing. Today, Android phones are thinner than the iPhone 5 and nobody complains. I just don't get it. You can bet your house the next wave of high end Android smartphones will be thinner than the iPhone 6. And if Apple drops the headphone jack they'll bundle the iPhone with bluetooth earbuds. (btw, if they do that it would also help to make the next iPhone waterproof).

The Macbook is definitely overkill but that's just one product. There's still Macbook Air and Macbook Pro. You can't stay still in this day and age. Other manufacturers do the same thing.

you 'have' a phone just because your friends do? how stupid is that. buy something because you like it, not to fit into a mold/crowd

Thinner for the sake of pure thinnest especially at the cost of other practical concerns rather than utility is insanity and a step backwards.

I think we should have phones designed to hold in the hand.

Samsung's A8 phone is thinner than the iphone, but is has a 3,480 mAh battery. Its specs may not be as good, but how is that possible? 

iMessage permits me to freely text with 2 of my friends that live in europe. It also helps me easily facetime my family that live on the east coast (i live out west). I don't own it to fit in. I own it because, given what my closest friends/family own, it is the best option. I don't judge my self-worth based on which type of phone I have. If my situation was as you describe, though, then I would completely agree with you, but it's not. 

My car only has an auxillary cable, no bluetooth capabilities. THis past summer, I drove from the east coast to the west coast (USA). If my phone did not have the headphone jack, I would not have had a 40 hour steady stream of tunes.  I need music while driving, thus I need the jack.
