Similar to how Windows runs on a computer, Android is an operating system by Google that runs on mobiles. In this awesome day I will present two of my favorite Android features; Google Calendar Sync and Google Contacts Sync.
Sync (or synchronize) means regardless if I edit a contact or add a reminder from my mobile or from my computer it will appear on both. To enable this feature on an Android device go to Menu > Settings > Account & sync then choose your gmail account, check both Sync Contacts and Sync Calendar.
One place for your phone book and email addresses, this way if you lost your phone or if it gets damaged you will automatically have a backup for all your contacts that saves you some drama.
Google Calendar (www.google.com/calendar)
Although I still use my pocket dairy to manage day to day tasks, I use Google Calendar to markup the events I cannot afford to miss and for recurring events (birthdays, blogging reminders, monthly fees..etc) it can even be useful in inviting others to a group meeting. One useful Android application is called Smooth Calendar, this widget shows upcoming reminders on home screen and serves as a shortcut to the calendar.
Not an Android fan? No worries, you can still sync Blackberry, iphone, Nokia and Windows deveices (here are more details www.google.com/mobile/sync). This time my special thanks goes to my lovely nieces Tala and Layan.
