An Android™ phone can also run multiple applications at the same time and in the background of a phone, making multitasking easier and the functionality of the phone more fluid than other cellphones.
Android™ phones are considered revolutionary in some circles because of its open source, mobile platform. All developers, whether professional or hobbyists, are encouraged to write programs and applications for the Android™ operating system and contribute to the evolving Android™ project by submitting them to the Android™ Market. G1 users then choose to download and use the applications on their phone by accessing the application library on their handset.
