Mobility, other than the initial move, is not an issue here, however, and would make me lean towards getting a moderately-priced laptop with decent specs with the largest screen/keyboard. And given that the packing issue is for a one-time transport with a short period of use until the OP's stuff arrives and can be addressed by a laptop that is smaller than her old desktop and monitor, almost any laptop today will accomplish the OP's goal without much of a size or weight disadvantage. I'm sure there are military-grade laptops out there that might weigh more than 6-7 pounds, but unlike 10-15 years ago, a bigger laptop and screen may not add much weight to the total package.

I like the Costco idea because you can test out the computer before you buy, and they have a great return policy. I also like the recommendation for a refurb business computer because it sounds as if the OP does not require cutting edge technology. I'd only add one more suggestion: is there a real need to buy the laptop before the move? If you need the machine when you hit the ground or if you're moving to an area with few retail options, then I guess you need to buy before, but if you can even go four or five days after arrival without a computer and you have the opportunity to do a bit of shopping, I'd consider waiting so that you don't have to haul the laptop with you.
