The Web-based PDA Equivalent

From Roy "Hi Sammy, Open Source scheduling systems, which make good use of AJAX, can, in my opinion, be the big blow to PDA's. They make data easy to collaborate on, they are portable and also quickly accessible (interaction equates to that of  Palm Desktop in terms of responsiveness). The features extend to a full diary, mail properly integrated, and more." More details
