Why can't you? It should work. Or are you saying you don't want to have the camera tied up? If so, again -- windows laptop, gigabit ethernet. One or two slots, live, showing up right on the desktop, instant edit, instant access. Under $600. Available now.
(testing will verify if this theory works, but I cannot imagine why it wouldn't)
In theory it works, however I would like to see a PC laptop coming in at 600.00 that incorporates:
Gigabit Ethernet
Firewire 400/800 On the motherboard or built-in
1 PC Slot (2 Would be ideal)
Post Pentium 4 processor
2 Gigs of Ram (Minimum for this application IMO)
The rest doesn't really matter, those are the core factors that will effect offloading, etc..
I do have an old Dell and while it's not terrible, I can see the differences in using a Macbook + ExpressSlot adapter with a built-in firewire out.
Not challenging anyone, just interested in knowing where that Laptop is and which company offers it at that price.
