I have a great desktop computer. Big screens. Powerful. It'll do all my image processing etc.

So I'm wondering about what would be the minimum I should be looking for in a laptop for imaging.

I know people's setups will vary, so I'll probably get a spectrum of views, but I'm curious about what exactly people's set ups are.

In the field, how many USB ports are generally needed for the camera, autoguider, control of the scope itself? i.e. what's the minimum number of USB ports I should specify when picking out a laptop?

How much hard disk space am I likely to fill in a night of image taking? Deep sky vs planetary etc.

Is image ACQUISITION particularly resource intensive? Would an old clunker do?

I don't want to drop big bucks and then find I could have run everything on an ancient eeePC.
