The calendar features standard icalendar import and sharing (although no syncing with iCal as of this writing), Email/SMS Reminders, and an innovative plain language event entry. For example, entering “Doctor Wednesday 3pm” would add the doctors appointment exactly where it belongs.
Backpack Calendar certainly overcomes some of the difficulties I’ve had with iCal in the past, most notably not being able to edit the calendars away from my Mac. It is not a free service, but it is available on all paying accounts. Accounts start at $5/mo, but to some having an online calendar may not be worth the subscription with alternatives like Google and Yahoo. On the other hand, if you already have a backpack account, this may come as a very welcome addition to an already excellent service.
So, how long before we see a nice dashboard widget for this? And once we do, will there really be any need for iCal anymore?
