Finding an app isn't hard. Just use spotlight or Siri.
Quick settings to toggle on and off? Why would IOS need that? Battery life is amazing even when leaving everything on. Android needs that to save battery.
Name a worth while widget. Just one. IOS you can get the weather quick via notification bar or Siri. Sports scores and schedules. What widget is out there that is must have on the Android that makes it so much better than IOS?
Back button? I had android and the back button is just one more button I had to worry about. I don't even see it as an issue with IOS but to each there own. I guess you go back a lot?
Worthwhile widgets:
1. The days schedule with meeting locations, times, people, which updates throughout the day. This is now added to the notification center via Google Now, so this widget isn't as neccessary as it used to be. Unlike with iOS, no tapping for a calendar or asking Sign via additional taps.
2. TV Favs widget, which lists the days upcoming TV shows that you like with times and description. Widget updates automatically as show times occur and allows for both LED notification reminder and custom sound alarm. Which means you can have the TV shows theme come on 15 or 10 or 5 minutes before the show to remind you what is coming on.
3. My Data Manager - shows you how much data you have used and updated hourly or daily. Can show you how much data you have used via wifi, roaming and data. Nice to see how much data you have used without having to call or text your carrier or drill through iOS settings to find the info.
4. Social app widgets - twitter, Facebook, foursquare, linkedin, etc updates via live feeds. If you use these apps, its nice.
5. Scrolling news feeds a la CNN ticker. Customizable for tech, local news, entertainment news and so on. Also gives breaking news alerts. No need to open an app.
Can you live without live tiles, Widgets, custom icon layouts, live feeds, etc and just have a grid of dead icons? Sure. That is iOS. And it is going on 6 years without change. Boring and stale are two very accurate adjectives.
