iOS 5 adds over 200 new features, ranging from things to make you more productive, to features that enhance how iOS devices handle the tasks they were already doing.

So, with 200 new features there’s a lot to explore. Here are the top 5 features we think make the update worth it:

1. Notifications

Now rather than pop-up notifications, the iPhone stores all your missed messages, calendar invitations, friend requests etc. at the top of the screen. If you’re already an iOS user, getting Notifications on your phone can sometimes be a hassle, just because they interrupt what you’re already doing on the handset. Now all your notifications are store at the top of the screen (like Android) and you can swipe down at your convenience to see what you missed.

2. Reminders

You always forget to buy milk while you’re at the grocery store, and forget to mail letters while you’re getting a sandwich at that place beside the post office. Reminders takes care of all that, letting you set alerts based on time and location. For instance, you can set up a reminder to buy Cocoa Krispies next time you’re at the grocery store, and next time you happen to be there the alert will go off on your phone.

3. Twitter Integration

iOS 5 - Official - Twitter
Love to get your tweet on? iOS 5 has built-in Twitter-integration, so you just have to sign into your Twitter account once under the Settings menu and then start tweeting directly from Safari, Photos, Camera, YouTube, and Maps.

4. iMessage

Spend all day talking to your friend who also happens to have an iPhone? iMessage lets you get your chat on with other iOS devices for free. You can “Talk to all your friends or family at once with group messaging. See who’s reading with delivery and read receipts. And if words aren’t enough, send photos, videos, locations, and contacts.”

5. Improved Camera and Photos

Now you can access the photo app from the lock screen on your iOS device, making it even easier to take picture on-the-fly. The volume button can be used as shutter camera-style, and you can pinch to zoom in and out to frame the perfect shot. Once you’ve taken your photos, you can touch them up directly on the phone and organize them into albums for easy sharing later on.
