Hi, I currently use a 24" iMac that I have been travelling with, checking it in as luggage. I love my 24" iMac, yet I'm wanting her to stay at home as a desktop and I am ready and have the resources to buy a laptop. I've been doing a lot of research and I still have lots of questions. I'm happy to find this forum, as I am hoping to get positive and helpful comments and buying advice. My 24" has 1T of hard drive space, and I use it for music production primarily. I use Abelton 8, Reason 5, and Record 1.5. I also write plays, and I enjoy using Pages as my word processor. I do edit some short movies using the old iMovie application (version 5.02) and I also work on my own webpages using iWeb. I am very attracted to the Mac Book Air because it is so sexy and also I tend to travel a LOT. I've owned two MacBook Pro's before, the 17" was stolen, the 15" had a liquid accident, so I got the 24" iMac so that I could appreciate the laptop once again and always have a great desktop. I'm ready for my laptop. My heart is set on the air. I'm not sure if it can handle my live performance needs - I perform with video, sound and also Ableton 8. I also would need to plug in my Novation Launchpad into the Air for live performance. I do know that the air will help me with the writing of my plays, as the lightness and size will inspire me to take it everywhere and work more while on the road. Yet, I found out that for about a $100 more, I can get a 15" MacBook Pro 4gig memory, 500gig 7200rpm harddrive. I already have a great case for the Pro, and that is the machine my peers tend to use to handle the music and video production software. Eventually, I'd like to get Adobe CS5 and FinalCutPro, yet that is about a year away. It be great if the Air could also handle those programs. Any power users out there who have truly put their wonderful Airs to the test? It would be great to hear from someone who performs live - using Abelton Live and Reason. If I do get the Air, I'm torn on the size. I found a SD card to Firewire adapter that would be great for me - one of my Audio interfaces needs firewire - so I'm more drawn to the fully loaded 13" Air over the fully loaded 11" Air. At any rate, either the Pro or the Air will be a lot lighter than lugging my 24" iMac around, which I have been doing for over a year now. Thanks in advance! I'm looking forward to your thoughts on Air vs. Pro - I'm ready to buy now.
