not sure cubase sucks but it's certainly irrelvant that it's an option.
I've long since given up on cubase. Right after I got protools free I knew what a "Real" DAW could do. I don't care for a multitude of windows for even minor functions that could all be one screen, you can't even extend notes by a small amount (something you'd do with string arrangements to make them more natural for example) without them extending right to the end of the track.
It's got too many windows to be usable for me, sure I could get a second display but that's not going to let me view and edit every audio, aux and midi track with full visual control over the automation, control data, notes etc... all in 1 easy screen is it ? Infact I'd say nothing touches protools for automation, it's hardly a feature hobbyists don't need, it makes manipulating effect plug-ins easier and more accurate, you can treat midi like audio and audio like midi, if you don't need score editing either protools is great. plus you've always got the option of using micrologic for midi duties if you need something a little more complex for midi, protools handles audio like nothing else.
There's been a lot of features added to Logic 5.2 that are making it more protools like by the day, if apple do something with that environment window to help you setup software synths with only a few clicks, I'll be looking forward to a new mac running protools LE, Logic, Unity Session and Soundhack all under OS X by this time next year.
Even now, with the burden of OS 9's archaic memory management and cooperative multitasking, I'd still rather use a mac for audio work than a PC, with protools LE getting more tracks and once we're under OS X, dual CPU and Altivec enhancements, I think the mac is going to continue to be the best plaform for audio even if you might be able to run a few more tracks or plug-ins on those other brands, you have very little choice over what you run the plug-ins and tracks under. Also with coreaudio and coremidi we'll be enjoying latency under 1ms and Quartz Extreme to give us more CPU power while the GUI runs off the graphics card.
I bet that guy with his dual opteron or whatever would think twice once we've got protools and logic running under OS 10.2 on 1.4Ghz G4s with DDR. With or without dual CPU support, from every Mac vs PC benchmark the G4, even with SDRAM comes out the same as an Athlon if you adjust it for Mhz. I'd guess a 1.4Ghz G4 would be at least as powerful as an Athlon XP 1900+, with faster RAM and other rumoured improvements to the PowerPC 74xx family of CPUs a G4 of that speed could even match faster Athlon chips aswell for all we know. The Pentium 4 isn't even an issue.
