We almost thought we were off the hook with these Latitude updates, after seeing the D520, D620 and D820 all receive Core Duo goodness fairly recently. Well Dell just revealed another Latitude in the works, the D420, which has a 12-inch screen and seems to hold up the ultracompact end of the spectrum. Not to be outdone by its larger siblings, the 420 will also include 3G data, but that's all we know for now. The notebook, which is due in about a month, was casually revealed during an on stage conversation with Michael Dell during the Future in Review conference today. Dell also mentioned that the company is doubling its India staff from 10,000 to 20,000 over the next three years, so get ready for some (more) hilarious phone support hijinks.
