I am a high school senior, and in one year's time I will be going off to college majoring in sound recording technology. The school doesn't have any requirements for the type of computer students use, and I am exploring my options. I have not yet decided if I want a PC or a Mac, but I am not looking for help deciding between the two. I would be using the computer for DAW purposes as well as everyday surfing, word processing, etc. I am thinking about Logic Pro (if mac), and Cubase SX 3 (these choices might change) I could buy a 2GHz 20" iMac G5 with 1gig of ram for around the price that I would be paying for super fast PC. That looks very good to me, but I have some concerns about the iMac G5. It looks to me as if there is no way to upgrade the iMac - the two firewire ports are my main concern, will I ever need more? (I know that there is no straight answer to this) One would go to an external hard drive, one to an audio interface. I am not too worried about this handling less tracks than a dual G5 power mac, I have read that the iMac will handle 24 tracks and up, and for now that would work for me. I would appeciate any feedback about the iMac G5 from experienced users, especially if anyone has had regrets about buying a computer with limited upgrdeability.
