Indeed Rainlendar is good tool but it's not good organizer. It's only fancy Calendar with ToDos and Events (maybe weather and clock too). For being good organizer some kind of address book is needed and better calendar views handling. I am using Rainlendar for a long time but it's painful when it comes to easy views switching. The problem is in it's working mode. Using Rainlendar as all time organizer would be as comfortable as sticking Hexelon to desktop and then making calculations.
The best use flow for such tool should be getting ann app in tray, use some keys (or click on icon) to invoke it. Later: click here, click there, minimize, "I'm done". Same as for Miranda. If I had to minimize all opened windows to send a message or browse options to get additional list view (week, month, day) then I would never install it.
Unfortunately: there is no good and free PIM application. You might not believe but I've tried dozen organizers during last three years (at least) and every single one of them was thrown away after one day of testings.
The reasons were different for various apps but the most similar were:
- crippled ToDo management,
- no password protection,
- address book issues,
- resources hogs,
- ugly UI.
I know that these reasons might not be the most important ones but:
- every task should have prioritizing and the possibility to specify reoccurrence patterns, tasks trees would be also nice,
- why should I write down personal info if I cannot hide it somehow?
- if there is no good search or contact's grouping then I don't need this tool,
- as small resources overload as it possible (i.e. Chandler is total mess with over 100MB HDD space and 40MB used memory used),
- I am not a fan of skinning but an app should not hurt my eyes if I am supposed to use it whole of the time (MSD Organizer thrown away).
Of course there are additional requirements which Ultima might give, like no external dependencies (.NET and Java apps).
The problem is also in double-licenced apps. Commercial versions are great but free ones are often so much cut that it is not even worth to download them. Take a look on awards winning EssentialPIM. It is good application but you have no possibility to change default events categories (or contacts groups) and no possibility to get tasks in tree.
The last problem is learning curve. Organizer should be easy to use and not require remodelling your brain (like Chandler does).
PS. It is not the final "NO". I am still looking for good PIM and as soon as I find it I will bother Ultima personally to add such tool
