Pro Tools has primarily always been about Mixing and Editing, Logic has always been primarily concerned with composing. It's always been that way, so i don't understand why people think Apple are changing tact, when they're simply advancing it further for creative people to futher evolve.
For that reason, Pro Tools has always been used in studios because of it's tight integration with hardware and industry leading mixing and editing environments, but many studios have Logic still so that they can take songwriters compositions and take them to the next level.
So, any 'pros' that i see on this forum complaining, i truly don't understand - It seems as though they want a Pro Tools rig, complete with an entire suite of sounds and plugins, wrapped up in a nice apple interface, whilst at the same time having linux-like customisation on the interface - all for the price of a drum synth.
Pro Tools exists for a reason, if that's the tool for you and you're purely about the mixing, then go get it, it doesn't make Logic any less viable for a professional composer. It's like touting Adobe Photoshop as kiddish as it doesn't do illustrator-like tasks. They are tools for distinct purposes at a high level, but are capable of overlapping adequately.
I could find tons of commercial tracks that have been mixed with Logic, it is capable, even Rhianna uses Apple Loops for commercial worldwide hits. And i'm willing to bet a huge amount of music has been written using logic.
