My mind is a little fuzzy on what I read and where I read it...
But I thought I read that for video capture, esp. HD, that it was better to get the MacBook Pro because the iMac had two firewire 400 ports that shared the same bus, as if they didn't on the PowerBooks with FW 800 ports. Shared-bus FW ports are apparently not good for HD video capture throughput? Further that the MacBook Pro had ExpressCard/34 to add the Firewire 800 omitted making for a sounder choice in the HD video capture, editing, devices, realm. It doesn't specifically bother me per se. I just thought I would ask since I thought it was an interesting discussion relative to the Mac and HD video editing which is one of the things I believe the 17-inch MBP is aimed at. 🙂
