Though for some time I have been reluctant to use Google’s applications because of some privacy issues, lately I have changed my mind. For example Google’s calendary sync tool for BlackBerry is simply indispensable to me. For the first time, I can manage my tasks and appointments with my mobile (Blackberry Pearl 8100), with a web browser (www.google.com/calendar) and with various desktop applications (I like Kde Pim). Furthermore, Google’s Calendar is one of the best web based calendar’s I’ve seen and it’s exported as both ICAL and XML. Give it a try !
