New Features and Improvements in Android 2.1 (Eclair): 
Live Interactive wallpapers:
The interactive backgrounds move in different ways: Some shift and swirl as you navigate around your home screens; others generate visualizations based upon music or finger-taps. It make Android devices look prettier. Animated wallpapers are onboard, and if you fancy it, you can interact with them too. For example, if you have an animated wallpaper featuring water, you can press the screen and ripples will appear.
Additional Home Screens:
Compared to the three home screens found by default in Android 2.0 (and the slightly updated Android 2.0.1), the 2.1 release of Android gives you five home screens to fill with shortcuts and widgets as you wish.
It means you can cram in more apps from the rapidly increasing selection on the Android Market, and of course shortcuts and Widgets. Although customised OS Android devices (such as the Milestone, T-Mobile Pulse, HTC Magic) did previously have more than three homescreens, they're now there from the off!
Updated Home Screen Navigation:
Along with the added home screens comes a thumbnail-based navigation system that allows you to quickly jump to any screen. You can still swipe left or right normally to move through the various screens, but the thumbnail system gives you the option to also see small icons of all five screens and tap directly on any one to jump straight to it.
Voice Controls for All Field:
Android 2.1 provides voice recognition for all text fields. Being able to control your phone via voice may not be at the top of everyone's list of features. Not only can you demand it takes you somewhere and be presented with turn-by-turn voice directions, but you can also send Tweets, SMS messages and emails just by telling your phone what you want to say. You can do everything from sending texts to writing e-mails by simply speaking the words into your phone.
New Widgets:
The Android 2.1 has same black-colored system widgets introduced in Android 2.0.1. Google has also added a widget that displays the latest news stories and weather on your home screen, then offers multiple tabs of news and weather information when opened in its full size.
Google Earth:
The Google Earth app for Android will launch hand in hand with 2.1, and it does look mighty impressive from over here. It's pretty similar, well, to Google Earth on iPhone, but there's a new mode where you can apparently fly through the air like a bird. Nice.
The phonebook on Android 2.1 devices will automatically pull in contacts from multiple sources including Facebook, and although it was a feature found on many customised UIs such as Motorola's MotoBLUR, having it natively installed makes it much smoother.
Android 2.1 will bring with it the ability to have more than one Gmail account working from the same inbox. This means if you have two Gmail accounts, you can get them both feeding one inbox, rather than having to set up separate accounts.
Weather App:
The new weather app as featured on Android 2.1 will include dynamic weather updates that use GPS to give minute-by-minute accounts of the temperature, humidity and weather conditions in your current location.
3D Photo Gallery:
The new 3D photo gallery feature introduced in Android 2.1. Google developed this system with Cooliris. This shows all of your images in a slick three dimensional view. Albums are clustered by time, date and location too, so your gallery will be perfectly ordered. It also integrates two-way sync with online photo albums stored at Picasa.
New App Launcher:
Android's App Launcher has been revamped so you no longer have to drag and pull to get to the app menu. Simply tap a button and everything smoothly zooms into place. Compared to the drawer-like look in previous versions, where the app list would slide up from the bottom of the screen, the 2.1 app launcher flies the icons in from the corners of the screen while fading in a dark background behind them. It then uses a rolling effect as you scroll down through the list.
