Netbooks

I"m looking to buy a netbook to take to the States on a 16 day holiday, part of which is the drive down Highway 1 ( Big Sur ), so loads of photos. Looking ,, naturally,, to store and view of an evening.

Was thinking of an Acer Netbook, simply because I have an Acer laptop and had no problems with it,, now I"m totally confused by all the harddrive/memory needed for such a thing, can anyone help me by telling how much of each they think I might need or if your using an Acer which model would be best,,

Trying if I can to keep the cost below £200.

Thanks for looking, rolandb
