I just bought an Android phone recently and I really love it. I just remember how I have difficulty explaining to other people, especially here in the Philippines (because we love Apple), on the definition of Android. I think it might be helpful that I share with you this helpful video and excerpts from www.android.com. In order to view the full definition, you may check this link.
What is Android?
Developed by the Open Handset Alliance, Android brings Internet-style innovation and openness to mobile phones.
Android™ delivers a complete set of software for mobile devices: an operating system, middleware and key mobile applications.
I am quite addicted to Android that I plan to develop some applications and games soon for Android phones. I hope I will just have enough time as I really miss doing hard core software development. I hope I still have my programming juices. Hope you can support my apps once it is developed. I hope we can have a lot of Filipino Android developers soon.
