Okay, here.s the deal. I edit video with Final Cut pro...currently on a G5 iMac 1.6ghz with 512mb ram. I am moving into a small [it.s nyc after all] apartment and won.t have room for my desk. So I.m getting a laptop. I can.t afford the powerbook...so scratch that. I.m going to get the iBook and put 1024mb ram in it. My question is this...the difference in MhZ between the G5 [1.6] and iBook [1.33] is not much...so speed on normal apps is not going to be an issue...but how much of FCP is optimized for the G5? Please don.t get off topic here and start talking about the 12' v. 14' etc...I just want to know if it will be a significant downgrade...I used to use FCP on a 1ghz powerbook and had no complaints...is it the same for the iBook? Thanks, Christien.
