Lightning
It's useless for me until I can sync it with my MotoQ
Pros: Colorful.. Very nice looking.
Cons: I will NOT pay BirdieSync $30 for something Mozilla should provide for free via extensions. I'd rather keep using Outlook.

Slow development + weak interface
Pros: - it's FREE
Cons: - weak integration of CalDAV
- very slow development process
- no advanced sync functions
- buggy

Not bad. Some missing nice-to-haves. Otherwise very solid.
Pros: Open format. So I'm no longer tied-in to MS Outlook. To use Outlook on Vista I would have had to upgrade Office 2000 (Outlook versions earlier than 2003 don't work on Vista. Then again, plenty other stuff doesn't work on Vista either.) Hence my switch to Lightning/Thunderbird.
Solid, stable. Never crashed yet in three months.
Won't be going back to Outlook. Not ever. I don't like having my mail and calendar locked-up in a proprietary format.
Cons: When a reminder pops up, there's no button to take you to the calendar entry. You have to open the main Lightning window and navigate via the calendar to the entry before you can read the description part of the reminder. I would add two stars extra if it had a button and/or displayed the 'description' field in the pop-up. No doubt the feature is coming.
There's no easy way to migrate from Outlook calendar to Lightning. So I had to type all my existing future appointments in by hand. (If you use Outlook's ability to 'list' all calendar entries, this is not as bit a pain as it sounds.) There's no easy way to migrate Outlook calendar to almost any other calendar program, so this is not a Lightning-specific problem - it's really an Outlook gripe.
