I assume you've edited them and want to maintain the edits.
If you don't want to keep them in a RAW format, you could obviously just export as jpeg/tiff/psd and then import them on the other computer.
If you want to keep them as RAW, go to metadata, xml, write xml data. This will ensure than any edits are applied to the image. Then just take the images from explorer and burn to a cd or hard drive and import them on the other computer.
No easy way yet, unless you have a external hard drive that can go between computers, then its a cinch, just move the files to there and import from there and it will be all kosher
