well i saw this unit at SMPTE and we transfered 8gb of DVCpro50 footage across to the store unit in 2 minutes... i saw it happening so theres no doubt that it comes in handy...

thing is , photographers use multiple CF cards and laptops or devices like the p2store to transfer images from cf to hdd on teh fly during a shoot.. gettin into this workflow wouldnt take long to adapt, so the next option if P2 is too expensivee is something like this.. i think it would come in very handy for those longform shoots..
