Just recently, Google hosted a big event launching its latest Nexus One, the first model created on the Android 2.1 operating system (OS). The event mostly centered on the Android 2.1 OS and what the user's can expect from Google's latest. And now, the developers and users can get their hands on the Android 2.1 SDK and start availing of its features. So what exactly would make users love this Android 2.1? Here are some of the features you might love about the new OS:

Multiple emails

The new OS is capable of opening more than one Gmail account via the same inbox. This is especially useful for people who have multiple Gmail accounts, which when you think about it is practically everyone. Hence, you don't have to make switches anymore, subtracting the hassle of setting up two separate accounts.

Photo gallery

The photo gallery will be grouped according to dates, time, and location. This translates to a much more coordinated album. What's more, you'll be able to do your browsing via a 3D wall, which Google has adapted from COOLIRIS.

Living wallpapers

Although for some, this feature could just be one way of wasting your battery, others may find an interactive wallpaper a novelty. Especially for those who want their phones to look pretty, the interactive wallpaper feature can be one of the most attractive attribute of the Android 2.1.

Voice controls

Some people count this as an amazing feature. Imagine being able to send emails and tweets via voice directions. Now, isn't that cool? You can tell the phone what you want and it will take you there via specific voice directions. With this feature, people could find greatly increased efficiency in their daily lives, not to mention that it sounds like something out of a futuristic movie.

Weather application

It provides per minute updates via GPS and gives information ranging from temperature and humidity in your location.

Google Earth

Granted, this is not entirely new since iPhone already has Google Earth. However, some users may find that Android 2.1's Google Earth has a few tweaks that put it a few notches cooler than iPhone's.

Automatic phonebook

This device is relatively easy to use. The only thing you have to do is sign up on your Google account via phone, and just like that, everything's updated. User friendly at its best, once connected, it can automatically pull up relevant information without too much problems.

The application becomes more efficient too. No longer do you have to drag--all you have to do is tap and the application zooms in. Now, isn't that great? There are actually various features that you might love about Google's Android 2.1, but so far these are the ones you might want to watch out for.
