I do not see how this is preferable to iCal. It is rather confusing I M O. The learning curve for a calendar ought to be shallow and short.

I like it but it is missing a critical feature that will prevent me and many others from using it....iPhone integration, especially with tasks. Numbered are the days of monolithic info management applications that only work on one platform. If iPhone and other mobile integration is missing it's completely useless to me. I suggest a Sunbird iPhone client that bypasses Apples horrible sync technology to offer a truly integrated solution offering contact, calendar, task and note syncing.

It's cross-platform, like Firefox. That's its main USP, and there are many situations in which it makes Sunbird (or Lightning, the Thunderbird plugin equivalent) very desirable.

Have to say I really like this layout and would gladly use it instead of iCal. The reason I went looking for an iCal replacement was due to the Info Drawer being removed from iCal 3.0...just couldn't live with all those clicks to get to an event's details. Drove me nuts. I installed 0.7 on a Macbook Pro (Leopard 10.5.0) and it seems to be consuming a lot of CPU. Over 100% at times according to Activity Monitor. I'm using the plug-in called Provider for Google Calendar 0.3.1 so maybe that has something to do with it, not sure. Keep up the good work. I'm anxiously awaiting the next update!

As always, I think it's great that the Mozilla team is remembering the Mac "five percenters" with every project. While Sunbird is clearly not ready to compete with iCal at the 0.2 stage, I can see its potential, and the interface alone is worth shouting about. If anything, all of us who use Macs at home but are forced to use PCs at work can get excellent alternatives to MS's crap browser (Firefox ROCKS on a PC), Outlook (Thunderbird's great if you don't have to network your mail folders) and now, with Sunbird, whatever the schedule program is that comes with office. Keep up the magnificent work, Mozillans! No problems with opening Sunbird here, but as I said, it's just a concept demo right now and shouldn't be expected to run alongside iCal. Looking forward to 1.0. . . .

Good for testing and getting the hang of, but do not import an existing calendar which has lots of events/alarms/etc. Sunbird will choke. Great start...oughta be a fine product by 1.0 stage.
