Best:

- Apple

- Panic (Transmit rocks, Audion was the best OS 9 mp3 player out there IMHO, and in general they're really nice and talented people)

- Hamrick (Vuescan is a killer app, exp. for OS X, and is updated about every five minutes [] ]'> )

Worst:

- Quark (can't believe no one else has named them yet)

- Symantec (terrible products, huge fear-mongers in lame attempts to sell their crappy software to OS X customers)

- Intuit (Drops much of their Mac support while their CEO is on the Apple Board - Niiiiiice... [xx(] ]'> )

Best,

Matt
