Dell low-cost Linux laptops

I'm glad Dell finally came out with a low-cost Linux laptop, the Inspirion Mni 9. I've been anticipating such a move for a long time. Now the OLPC XO and Eee PC (which is getting better, by the way) finally have some more real competition. I think this space is one to watch very closely, especially with the floundering economy, increasing globalization, and increasing technology adoption across borders and socioeconomic groups. Is ubiquitous computing really almost here? Are other variations in the works? Will we see more cross-breeding between these low-cost laptops, portable game devices, and smart phones?
