(The 43Folders people are crazy about productivity and Getting Things Done, so they know a thing or two about being productive.)

Anyway, the best line in the article (I thought):

When I swtiched I thought I will lose two mounths looking for some kind of remplacement for my old-loved PC's applications. I don't lose even one hour. You have mail, mozilla, firefox, Safari, Newsfire, Fireworks, Pages, Word, Keynote, Excel, ICal, Itunes, BBEdit, Transmit, an another million of application waiting for you out there. Most of those are free (or $20.00!). I can't say how much I miss my old PC applications, because... I DON'T REMEMBER!
