I have to disagree with the negatives on here, based on my own experience. I have become disillusioned with Daylite and Contactizer, both of which I have shelled out substantial sums on. Contactizer seem to be disregarding Apple's Mobile Me changes and Daylite seem to want me to use Google Calendar, even though I don't want to.

Soho Organizer, on the other hand have responded to Apple's meddling and produced what is, for me at least, a clean, quick and stable App that does exactly what I need without work arounds.

I also had a rapid fire exchange with the Chronos support guys before I forked out on yet another PIM/CRM style product - they were answering within minutes and were incredibly helpful with their responses.

It seems not everyone has enjoyed the product or the developer's service as I have over the last few days, but I am now very pleased to say I have just bought a family pack for use in my charity.

I can only speak from my own experience, and based on that I would have no hesitation recommending Soho Organizer.
