It's probably for profit reasons, but I thought it might be because having a 12" netbook in Dell's lineup would be blurring the lines between notebook and netbook too much, potentially confusing consumers. Does anyone else think that a 12" screen on a laptop gives people the idea that this could be their main machine? I've certainly had non-tech-savvy friends ask why they shouldn't just buy a netbook to replace their main machine (it was actually the Dell Mini 12, in one case).

It's probably the profit margin thing, though.
