I tossed Ubuntu (with ext4) on my 2005 laptop, and it's proving to be a formidable word processor and web browsing machine. I think a lot of people are just realizing that they don't need another core or a chip built with a smaller process to play flash games and write e-mail.

Though I'm a little concerned about what the smaller number of hardware sales will do to development in the server market. Can they maintain R&D budgets?
