Ranny, thanks for the reply. I think what I was trying to convey was my hesitation to go back to Outlook. I was hoping here might be a "better tool" with the ability to nest tasks and projects. After sending I did realize my syncing of tasks is working fine between BB and Outlook. My hesitation to use Outlook stems from a few scenerios that probably won't occur too often and I now fell are not showstoppers. They are
1. Storing personal stuff on work outlook
2. Being disconnected from Outlook while at a client
3. Using a "flat" Project and NA list as opposed to a nested hierarchical Project and NA List

After thinking about this some more I belive Outlook will work for this
1. Just get over putting most personal stuff on outlook (exception is my very detailed music and guitar studies - I'll try Thinking Rock for this - more on this below)
2. The BB view of tasks isn't as great as Palm or DateBk but I is usable as a way to view. In a pinch I could see using it to enter an idea for a project or NA. Web outlook which is usually available at clients is also a way to enter new tasks/projects. I can clean up the entry and categorize later when I have a direct connection to Outlook.
3. Much of my day to day work projects can be organized in "flat" manner via Outlook. My r&d on other tools like Todoist has also taught me more about tagging and labels. This could be added to projects and na's when needed in Outlook

While Todoist could nest projects and tasks I never felt that I had the right level of visibility into all of my commitments. Also, while using Todoist I disconnected from using my Outlook Calendar and taking advantage of the BB access. Even after actually looking at Todoist's mobile page I think I will be switching back to Outlook for most of my GTD implementation

For some personal stuff like my guitar playing I am going to try out Thinking Rock combined with a paper based journal. I may put some type of place holder project in Outlook just to remind me to include this in my weekly review. My music projects lends themselves to more hierarchal views and they are less date driven. By shear volume I would clutter up my work Outlook too much with music related projects. I also found that firing up Outlook to track my progress on learning cool guitar riffs is not exactly inspirational.
