However you configure it, though, the Dell Latitude E6420 AGT is clearly meant for corporate users who want a machine that can not only survive rough-and-tumble conditions but also crunch serious numbers over a full day on the road, whether a power outlet is handy or not. Unless you need such a seriously sturdy, powerful laptop (and you don't mind lugging it around), you can probably find acceptable alternatives (including other Dell models) for a lot less money.
