Am I the only one who can't stand their interfaces? It looks terribly out of place on OS X (the icons, those tabs!). I don't know why it seems every app built on Java has to look like that.
I'd rather have a good and usable tool than a pretty one; instead of wasting time fighting unsupported bindings or trying to replicate them (likely poorly).
Being cross platform has it's issues, see iTunes on PC? However Adobe seem to do a decent job, perhaps being a creative company helps.
