Why do you need to print the manual at all? It's so much easier to reference the manual while you're in Logic on your Mac while you're trying to figure something out...
Oh dear, not this same old argument again .....
You can read the manual in Bed or anywhere without having your computer on. You can have the manual open beside your computer and access both simultaneously. Some people prefer that.
The manual is not even really that useful unless you're in front of Logic...
On the contrary, the manual is IMO highly useful anywhere so long as it gets read. As a case in point, I am working my way through the Apple Pro Training Final Cut Pro 7 book right now. A three hour flight on Ryanair last Sunday evening was put to good use by doing just that. Opening and using my 17" MBP would have been impossible given the somewhat cramped space on those aircraft, I still managed to work my way through a couple of chapters and learned a few things.
Ever heard of recycled paper? There is also the idea that reading a printed manual can save electricity if your computer is switched off. That in turn can save Coal, Oil, Gas, Uranium etc.
Basically these sort of arguments lead nowhere. I believe that it simply boils down to whether the individual prefers printed manuals or pdfs or both. I appreciated having both with Logic 8, and I certainly miss having both with Logic 9. In fairness to Apple, the cost of the bundle of manuals that used to come with Logic, and Final Cut Studio must have been considerable, and especially bearing in mind that Logic Studio now costs a fraction of what had to be forked out for everything back in Logic 6 days, to an extent understandable, if still regrettable.
