Cons:
No indicator light for missed calls/texts, etc.
Wish the screen was a little wider, taller only, come on...
Apple to please stop with all the restrictions. Example: you can't download a song/ring tone directly from the internet and assign it as a ring tone. You gave to jump though tons of hoops with an app, conversion, hook up iPhone with iTunes, move the file back and forth, then able to assign the file as a ring tone. There are several more...but I don't want to get into it.
Customization of the home screens, etc. like Widgets.
Notification pull down menu... add more notifications.
Need USB/Micro USB standard so I can use ANYONE's charger and not have to carry my own lightning cable or purchase a second one or another adapter. 30-pin, lightning to USB/Micro USB, etc.
When I plug the iPhone into a computer, let me have access to other parts of the phone besides only the pictures.
Able to attach a Word/PDF file in an email etc.
When I see an address, be able to touch/press it and it will open up a map so I can see where it is on the map. (This one is hit or miss)
Able to add more than 1 (or is it 2?) work numbers in the contacts list. There are some businesses that have several numbers to a business.
Able to play more file formats of video without having to download another app or converting all files to an Apple format to be able to play it o an iPhone.
Wish Apple would be a little more innovative or rather than play catch up with the other manufactures. Come one, 2 years to get LTE?
Pros:
Build quality assuming you get an non-scuffed, non-nicked, non-scratched phone.
American product (even though it is assembled in a foreign county).
Warranty (Apple Care Plus) and local stores.
Apple has better refurbished/re-manufactuerd phones (warranty exchange/repair) compared to other manufactures/companies.
Better resale value.
That is all I can think of at the moment.
(flame suit on since I know no one wants to hear the cons of their phone
)
