Definitely eBird! It keeps your life list and can be broken down into state, country, hemisphere, ABA area, AOU area, etc. AND it has the added bonus of contributing your sightings to science.

Birding friends,

One of these days, I'll be organizing a binder full of too many notes and
checklists into one decent life list.  I'd love to hear your thoughts on
what works for you -- software you've purchased, online service, customized
Excel spreadsheet.
