Outlook is still the best email/PIM I ever used but I only use it at work where they are paying for it.
I’ve been using Thunderbird with the lightning addon for 6 years now and I’m very happy with it but I’m eager to migrate away from all my mozilla stuff. Palemoon is a fine substitute for Firefox.
Any word if Fossamail is going to go portable?
I think it is so new that we will have to see or email them...
