@email (separate from computer as i have a blackberry so i can crash thru a lot of emails while traveling)
@home office (bills/mortgage/financial planning/filing at home/some calls that need info that i have at home rather than with me
@home (stuff at home not in home office -- yard/fix it jobs, etc)
@online -- web browsing -- some email where attachments are necessary
@rd/rev/decide -- general category for reading / reviewing/planning/deciding items -- if somethings stays too long in here it will start to putrefy and stink, so it's a dangerous parking place for next actions.
@wtg -- waiting on stuff (i also put delegated projects in here.
i keep someday/maybes and project lists elsewhere so not to clutter up todo application in palm with anything but next actions.
@office (don't use this one much except when i need to run a big copy job or something that requires stuff i have in the office and not elsewhere)
