A new product from Chronos, SOHO Organizer, has been released by Chronos. It replaces their products Personal Organizer and Group Organizer. I have spent 15 minutes with the calendar/task list component, and I recommend staying away from it, for two reasons:
1) It has very little value. It uses (or interfaces with- not made clear) ical. What you get is a list of your calendars, both appointments and tasks. You can look at all calendars or one calendar. The list of calendars (categories) is neither alphabetical nor in the order you arrange them in ical. While this is not much, the list is a view you don't get from ical.
2) It is slow as molasses. I am using a one-year-old Powerbook, not a speed demon, but.. when I click on an existing entry, I consistently reach one-thousand-and-twenty before a window opens. This occurs even if I immediately re-open the same entry. Adding an entry is faster, only about 10 seconds.
Chronos wants $50 for the calendar component, and $100 for the suite, which includes a contacts module, a notes module and some printing thing. The contacts modules seems acceptable in speed, unless you want to create a task or event from it.
I have been using Sticky Brain. another Chronos Product, for some time and think well of it. The SOHO Note component is intended as a step up from that product. I have not tried it, and may not, because the calendar component is so poor. The company went 6 months between announcing imminent release to actually releasing SOHO Organizer. Frankly, I would be ashamed to be asking people to pay me for such a poor product.
