[Mr Rob]

When I first started into perspectives I found that the temptation was to create lots. Partly to experiment and partly because of "ooh it can do that too!" syndrome. So I ended up having to wade through a list of perspectives to find the relevant one...not good.

Having experimented with pretty much every possible approach, these are the ones, I ended up genuinely using, and have kept (they are in line with what whpalmer4 suggests):

1) Today
All available tasks organised by project (works on iPad)
Based on the MacSparky recommendation.
Review it every day and then use the Start Date function to "tickle" items I know I am not going to get done today either due to time or knowing I will not be in the right context.

2) Due.
All due tasks.
Organised by due date.
Pretty self explanatory!
The Forcast view covers this as well, but I have never really got on with the Forecast view...I like a simple focused list so Forecast actually has a bit too much going on for me.

3) Waiting For
All tasks with a waiting for context.
Organised by context as I use hierarchical contexts to sub divide waiting for into various people I work with, my various clients, companies I regularly shop from online, etc
All of these are inherently not available / oh hold so perspective was created to show "remaining items".

4) At Office
My work catch-all list.
Only available tasks that I could/have to do at the office arranged by context.
Calls, at computer, meetings, things to discuss with/delegate to colleagues, emails, things I need server access for, things I need office based software for, etc, etc.
I arrive at work and flick to this and work through them.

5) At Home
Only available tasks that I could / have to do at home.
Arranged by context.

6) Errands
Combines all my errands contexts (bank, post office, supermarket, shopping, etc) into a single view for when I am out and about.

I do also have a personal perspective which is a list of music I want to buy - vinyl junkie! Basically shows a simple alphabetised list of all the records in my "Someday Maybe" music list. And it only exists as a quick access short cut...so I don't have to burrow down through the folders and projects to get to it.

Every other perspective has been deleted over time. Just don't need them.
Though I do live in the ones I have when I am working - one tap on the side bar and I have the relevant list of what I can do where I am.

I am lucky enough to own OmniFocus on Mac, iPad and iPhone and the way I have quite naturally ended up using them is:
- Mac for organising, project planning and reviews only (it is never open when I am working as it is too cumbersome and means I have to switch windows).
- iPad for getting stuff done - it sits in front of me on my desk or walks around the house with me. It tells me what to do next and it is where most things get checked off. It is also where most work things get added to the inbox throughout the work day.
- iPhone to nag/remind me (it is the only version that has alerts set to "on"), act as my quick access list when am doing errands (or my all important music shopping!). And it is great for quickly adding things to the inbox when on the move.

Good resources for perspective set ups are Mac Sparky, Kourosh Dini's e book "Creating Flow with OmniFocus" and simplicitybliss.com.

Hope that helps.
