Long time heavy duty MS Outlook (OL) user for GTD purposes. Use tasks function intricately interwoven with calendar, email.

Have been using Blackberries (BB) for 3 years that sync some, but not all info w/ OL.

Now have iPad2. Can access full OL through Citrix
Plan to switch from BB to iPhone5 when it's available.

Any prediction how good an experience Omnifocus would work for me on iPad/iPhone? I do NOT have a Mac....but perhaps could be persuaded

Thanks, TJ
