I am a user of Outlook Tasks and mulling over an iphone. I realize that synching my Tasks to an iphone isn't going to happen. I am willing to ditch Outlook Tasks and migrate it all over to Toodledo, but I have a big issue I hope someone can help me get over - what happens if I don't like Toodledo and want to get my huge amount of Tasks back into Outlook? I know I can easily import my tasks from Outlook into Toodledo, but can I do it the other way in case I want to? And what happens if one day i wake up and Toodledo (heaven forbid) isn't there anymore? Are all my tasks gone? if you guys could shed light on these and make me feel better i can take the leap - and get my iPhone!
You can export your tasks from Toodledo in a number of formats (e.g. XML, CSV, TXT, iCAL) and there is also a backup feature so your data is safe. Once exported, you may need to move a few columns to import back into Outlook.
As a former WinMobile phone user, I can say that iPhone is great and works well with Toodledo. In addition to Toodledo's iPhone app, you can also use Appigo Todo among others.
iPhone also works well with Exchange/Outlook for corporate calendar and email. Guarantee you won't look back. I liked the iPhone experience so much I recently migrated my home computer from PC to Mac.
