Likes:
* Smooth and simple to operate (why have menus upon submenus when they are not needed, "any fool can make something complicated, its harder to make something complicated simple").
* Pretty much never needs a reboot (something I know is commonplace on Android when this and that stops working as it should).
* Quality and design of the hardware, and a good example to other smartphone makers that having the highest spec makes no difference whatsoever.
* iCloud: Absolutely brilliant IMO, had to replace my handset after drowning the other in the Mexican sea. Watching it restore every last contact and setting right down to the wallpaper is a wonderful thing. Within no time I felt like I had the same handset as before.
* Ecosystem: Sitting on my sofa and using my iPad, iPhone, and Apple TV all working together in perfect harmony.
* Apps: Little needs to be said here, so many, and much more polished that their Android counterparts pretty much 100% of the time.
* Aftercare: When you by an Apple product you KNOW that you are in good hands if anything goes wrong. Watching people get handset replacements etc at the Genius Bar without having to put up a fight is one of Apple's very strong points.
* Oh and I like the way that Apple do their own thing. An iPhone doesnt have every feature that an Android does because Apple arent trying to make an Android phone. They are very focused on the product they create.
Dislikes:
* Slightly small screen, but Id only want slightly larger. The 4" screen on the next iPhone sounds like it will be ideal for me. Don't need a phablet. However whilst small, its incredibly high quality which very often offsets its size for me.
* Slightly restrictive, but I understand the effectiveness of a closed ecosystem. Ive un-jailbroken my iPhone's many times because honestly I really don't need all the fluff.
