Software products that you think are really good

[talentdeficit]

i am mostly a mac guy, so some of these are osx specific.

xylescope

this is, without doubt, the best css editor ever. it's insanely fantastic.

xcode

my favorite ide. i can't believe someone upthread mentioned eclipse.

colloquy

a decent irc client for osx. decent is about as good as it gets in this domain, unfortunately.
