You want tips and none of the other posts gave you any.
Here are my tips:
1) Don't go in expecting it to be "like iOS". Alot of things are similar, alot of things are not.
2) Configure your home screens BEFORE downloading all the apps you want. For example, my S4 came with like 4 or 5 home screens each with it's own widgets that Samsung was trying to hype (like Samsung Hub). It was a strange experience coming from iOS because once you log on to iOS, your Apple apps are just there. Samsung out of the box was kind of all over the place. Here's how my 1st home page is setup:

3) Configure your phone to how you want. Set the rings tones, vibrations, wall paper, etc.
4) Download your apps and organize one page at a time. I add a home page once at a time until I filled it up with the apps I wanted. My 2nd home page are my most used apps from top to bottom, no widgets and looks exactly like an iPhone app screen. My 3rd home page is Games. That's all I have. All of my other apps are in the app drawer.
5) Log into all your accounts. The great thing about Android is that built in accounts are there. You won't have to keep logging into your accounts all the time. The other great thing is that you can share things to other apps with ease. I love been able to read an article on the web and "share" it to Evernote, or to Pocket if I don't have time to read it all. When I go to open Evernote or Pocket, it's got everything I saved. You can't do this on iOS.
6) Load your music and photos and videos. Here's were people fall apart during the iOS to Android transition. It's nothing like iOS and iTunes. I'm not sure what software Sony gives you, but you can
6a) download Google Android transfer app to your Mac (if you're on Windows you don't have to worry about this) which gives you access to your phones file system. Now you can drag and drop your iTunes music (open your iTunes folder, navigate to iTunes Media>Music) to your Android music folder. I have an SD card for my S4 so I just have a folder on that label "Music" and drag & drop everything to that.
6b) If you have Playlists you want to transfer you can 1) download and install iSyncr to your phone and your desktop 2) Use Google Music to upload your iTunes library to their servers. It automatically brings all your playlists with it. I personally use Google Music as my default player, but I don't use it to sync my iTunes as I have way more songs than Google allows (20k). I've got about 8k songs uploaded to their servers, however and it works like iTunes in iCloud. I can download my albums (if I don't have it on my SD card) simply by "pinning" the music.
7) As for photos, I have a folder system on my iMac. All my "events" are basically 2013_Wife's Birthday. I just drag and drop those to my SD card's folder called "Photos". If you use iPhoto as your only photo storage and organization, this may be a problem.
I must admit, with iTunes, Apple has the transfer of media to your device down pat. With simple checking and unchecking boxes in iTunes, they made it damn easy.
8) Configure your lock screen. I use an App called Dashclock and it gives me a nice clean lock screen (I just have the time and date and weather). On Samsung, however, it doesn't work if you have a PIN or Pattern setup and defaults to Samsung's lockscreen. I hear that this doesn't occur on other Android phones so this may be a Samsung thing. I guess when Samsung means PIN enabled lock screen - they truly mean it's a lock screen.
9) Enjoy that big beautiful screen. The S4 screen is gorgeous to look at. Big, bright, and beautiful. If Apple ever made a proper screen that's not so narrow and makes 4.3" or bigger, I'll be back. But as of right now, I love my Android phone and it's ease of sharing capabilities.
The apps, however, perform the same function on platforms (Facebook is Facebook) so it's a non-issue. Apple MAY have a slight advantage because now their apps have an iOS 7 "look" to them and I don't think devs will copy that look to Android. Android apps will start to look like Android apps and iOS 7 apps will look like iOS 7 apps, just was Windows apps look like Windows apps. I think it was a good move by Apple to separate their products from Android because both platforms had the apps looking the exact same.
