maybe off topic for here, but just about fits
Having 'been digital' for a few months now I am finding my poor old laptop just aint up to the job of keeping up with storage, processing Raw or having enough screen space (heck 12.1" always seemed enough before)
So I am wanting to get a new machine, but it must do twin screen so I can have photo on one screen and all the RawTherapy or whatever dialogue boxes on the other (got twin screen at work and I would not go back to a single by choice)
Simple question really, can I do twin screen with a laptop (even laptop screen for dialogue boxes and calibrated external monitor for pics) or do I have to buy a big PC box with clever graphics card ? Googling got me no where and I wouldnt trust PC World to be able to answer the question. Or is there a good process/edit/store setup I have not thought of
all advice welcome (within reason)

except maybe about Mac stuff as I have to use Windows kit to be able to 'work from home'
