Well given the serious responses from this post, I think it is pretty obvious that the BB needs a FULL featured PIM app such as this.
I do like Pocket Day, and coming from Palm OS and Agendus -
Agendus for Palm OS Professional Edition - The ultimate personal information manager for Palm, links and enhances Meetings, Tasks, Memos, Contacts, Email, and powerful wireless services please see this product, I feel that you need to really improve the PIM aspect of it in terms of Calendar/task management.
Why improve on an already great email device? If we want to have email support we just goto mail application, I don't think you need to improve that section at all. It's the basic contact, calendar management that needs serious attention.
You can really learn from the Palm OS in that they put the PIM aspect up front to manage day to day items, people, etc.
The BB already has a great email application so no need for further fuss with it.
Please bring new, fresh ideas to the Calendar and Task sections like -
1. Icons set - basic (for meetings)
2. Easier editing of items within PD
3. Drag and drop items, highlight/hold trackball - rescheduling
4. Pop up calendar for editing/moving items
5. Year view?
6. Linking items - as mentioned - (tasks, contacts)
7. Filters! - by category
8. List of events - i.e. Birthdays
9. Create item with Contact from address book, i.e. appointment, task to do
10. Edit items within Pday! (appts,tasks) without going to native BB app.
Thanks!
As always, thanks for bringing a great needed product to the BB
