Thanks for the replies and suggestions so far!
Your at a mac forum full of people who love OS X, were gonna suggest OS X over anything else, if you want OS X get the macbook, if you dont care get an HP
That's what it will come down to. You folks can stop the "Windows/Vista is bloated crap" arguments though. I'm very adept at configuring it and neither stability, performance nor bloat are problems here. So in don't need anything "dumbed" down, but still welcome good design (as in usability, performance and looks). I'm curious about OS X, but I also already know it in parts from my band-mate. Actually word goes that lowest latency performance for audio-interfaces is still a bit better performing on Windows ASIO compared to OS X core-audio.
"Usability" doesn't matter much though once I start my software. Because all the audio software I'm currently running on Windows will work just the same on OS X besides the menu bar acting different. For a musician his Digital Audio Workstation (DAW) software effectively becomes his "OS" from where all plugins and controls are run. The inclusion of well specified IAC virtual Midi ports is a big plus on OS X.
But it's not only about the OS, Macbooks have been used on stage by thousand of musicians worldwide which means you know you are buying a working solution. On the other hand the new MBPs are first generation products, so I guess the latter argument is only partially true. One important piece of software called Max/MSP runs more stable on OS X and offers slightly more features. That is because it's an original Mac application that got ported to Windows.
Someone mentioned how the Alu Mac can get hot on your lap because of the Aluminium being a big heatsink. I can imagine that this is an advantage on hot stages where any kind of additional cooling is very welcome. If that keeps the fan-noise down it also is an argument for home/studio use where the laptop is sitting on its stand and an external keyboard is used. My current desktop PC is very quiet both because I prefer it that way and because I do recordings right beside it.
I don't care much for the "I" stuff, I'm an owner of Office 2007 Professional on Windows and I will likely get VMWare or Parallels just to be able to use that without Bootcamp.
I'm still waiting for shops to get their demo units so that I can have an actual look at it plus I'm collecting informations and doing calculations on the price point. My current conclusion is that if I buy a MBP then it either has to be a new 2.8 Ghz model or a last gen (refurbished) 2.6 Ghz model. The new 2.53 ones perform slightly worse for my kind of applications than the old 2.6 ones.
