pretty much sold on the 17" iMac seeing how my 17" WS display is the only thing i really want to keep from my current setup and i can use the desktop extender option. couple of remaining questions: 1. what's the difference in the fw speeds (400vs800)? i noticed the imac has 400fw ports. is this speed sufficient if at some time i decide to use external storage to view/edit video? 2. concerning the bluetooth setup, say i get the imac with wireless mouse/keyboard, and one day decide to put a mini in for the kids within close proximity to my imac. will the two bluetooth devices conflict if both are setup with wireless keyboards/mice? to clarify, if i'm surfing on the imac will the mini be awoken from the bt activity 5' away... 3. on the 17" imac, will 1gb ram be sufficient to start out? i plan doing a bto with 1x1gb ram installed and possible adding another gig later. didn't want to get the 512mb stick only to replace it or mismatch with a gig stick. 4. iWork...how essential is this app? 5. any guess on leopard's release and once released will it immediately replace tiger in units shipped or does apple have to sell off all the imacs in inventory that already has a tiger disc in it?
