personally i love logic. but if you dont have a mac already then i would find it rather pointless to buy one just for the sole sake of using logic. theres plenty of good things about those other programs. plus its all about personal preference.
but those fuckos over at digidesign will have you spending money out the yang-hi if you want anything outside of standalone pro tools.
Doesn't matter what you use. Everyone has their own preference.
Use Reason, FL, Cubase, Logic, PT whatever, or a combination of them.
If you're tunes are whack, they're still gonna be whack no matter what program you use (not saying your tunes are whack mate don't worry hehehe)
The point is, these are only tools to get the sounds in your head into sounds you can hear
If you're relatively new to production then I'd suggest Reason or FL, though some people find they gel better with Cubase etc.
Get some demos mate and see what tickles yer fancy
Im with you on this one. I started making music on a windows machine. Bought 6 before i purchased my first macbook. man i should have saved my cash and just bought a mac t begin with. its one of those things you dont know until you try and learn.
there are great things about all DAWs out today as they continue to gain mass sex appeal between digital producers and the likes. now with intels in the new os x computers the sky is the limit... oh and i get no more pops and clicks thanks to outdated hardware
