Caddstudio and others looking for a Sidekick replacement,
I'd been a faithful Sidekick 95 user for years until I upgraded to Win XP Pro. With lots of data inaccessible, I started searching for a replacement, hopeful that my Sidekick data could somehow be imported. I didn't find that panacea, but I did come across AnyTime Deluse 8.3 from
designed for Windows 98 and later versions up to XP. Then I stumbled onto this forum, downloaded Sidekick 98 and regained access to my data. The failure of ToDos to carryover prompted me to look more seriously at AnyTime Deluxe and it has a lot going for it.
PROS
As for To Dos, it has lots of options to set recurring ("repeat"

items and I like the fact that overdue items persistently come up daily in an alert window where you can selectively mark them done, carry them over, update or delete.
You can send e-mails from the Address and To Do Details windows and, from the Address Details window, you can also launch a Web site or even get MapQuest directions for the entered address. You can also download schedules for major events, such as major sports schedules.
While I'm not a Palm or other PDA user, I've checked the documentation and there's a program (AnySynch) that purportedly will synchronize data for many PDAs.
CONS
1. Obviously, the biggest one is the migration of data from Sidekick to AnyTime. The good news is that I at least have access to the data now and I've been able to dump a lot of stuff that was obsolete.
2. You can't configure recurring items to repeat "indefinitely." So, if you only go out a year or two, you might inadvertently drop still active To Dos. It's possible there's an alert before that happens, but I haven't gotten there yet.
3. While you can assign a contact to a filter Group, add new Groups, and turn the filter on and off, when the filter is "on", you still have to go through each alphabetical section of the Address Book to see everyone in a selected Group.
CONCLUSION
Overall, I see more pluses than minuses, and it's supported!
