Mine has ended up as @computer - for most items; longer more complex items that need more concentrated effort are moved to @quiet(c) so I know I can only address these when office is emptier or when I know there are less interruptions agead of me; and finally @computer* which means really quick or almost mindless - like printing documents, scheduling appointments, setting up meetings, out of office assistant or very short replies that I couldn't do immediately when processing tasks.

This is an interesting thread though - helping me to re-examine which ways might be better as my approach kind of evolved but I've not evaluated it really. Seems to work most if the time but sometimes putting things on the @quiet list makes that list grow out of all proportion!
