Ahh, well not surprising that it was discontinued, I imagine it is a very niche item. It does seem to still be available on dell for the time being, so if that is something that interests you, get it while it's available.
The next option is going up to a 13" ultrabook, in which high performance parts are more common, and made by a number of more affordable manufacturers. Not quite as small as a netbook, but still designed to be portable and lightweight.
