Hello, Does anybody have experience using OsiriX on a MBA? I'm either going to get a maxed out 13" MBA, or a 15" MBP. I would love the portability of the MBA, but would like to know how fast it runs OsiriX, as this will be the main program I will need to utilize. I read reviews that indicated 3D rendering and DICOM set transfer can be slow, but this was on older MBA's. Of note, I will be importing my DICOM sets from an external CD/DVD drive (not via PACS transfer). As for the 15" versus 13" MBP - I figure if I am going to lose the low weight advantage of the MBA, I might as well get a little more screen real estate. One more thing. For most of my viewing, I will be connected to an external monitor and will need to use a mouse (while having my external CD/DVD drive plugged in as well). I still need this computer to be portable, though, for other reasons. Thanks in advance for any advice/insight.
