The look and feel of Android’s main screen has definitely evolved from version to version. Following figures show the main screen of Android from version 0.9 and how it changed from earlier versions.
Figure 1. Main (Home) screen of Android in version 0.9. Only the primary applications (Dialer, Browser, Contacts, and Maps) are shown. The Menu tab holds rest of the applications.
Clicking on the Menu tab on the main screen opens up the icons for rest of the applications.
Figure 2. Applications on Google Android phone. This transparent window is shown when the main tab is clicked.
Now let’s see how the user interface of the main screen has evolved.
Figure 3. Android’s main screen has gone from a Mac style Dock to iPhone style display of icons to, perhaps, its own style
As you can see in the above figure, the original main screen interface sported dock, that you would see on the Mac OS. Then in the version m5-rc14, the user interface became a bit like that of iPhone (big icons of applications on the main screen). And the latest version is similar, but most of the icons need to be pulled up from a menu tab.
The dialer sports a sleeker look as well (in Android version 0.9).
Figure 4. The dialer with Call log, Contacts, and Favorites in the top tab in Google Android version 0.9. A bit different in earlier version.
As you can see, a cooler/darker user interface made it to the latest version. Older version had a lighter look. These are the default user interfaces.
The Google Maps
Google maps, of course, look the same in different versions of Android. However, in version 0.9, two new menu buttons have been added: My Location and Map Mode. The Map Mode has the familiar mode: Map (standard map), Satellite, Traffic, and Street View.

Look and feel of the browser remains pretty much the same, except for the subtle differences in the menu.
