i was using xtunes, but there's some fatal flaws - you have to press a combo of keys to use it, whereas synergy can assign basic controls to F-keys (f13 to play/pause, etc), also the fact that xTunes uses black or grey text instead white means it's mostly illedgible ontop of web pages. synergy is very good, but there is a 5 charge for it. maybe i should just pay it.
