The Latitude 7000 series has been Dell's flagship business laptop lineup for a few years now, and this year's 7400 2-in-1 manages to further improve an already excellent design. Its predecessor, the 7390 2-in-1, has all the security and manageability features that IT departments need, but for all its useful features, it's still part of the old guard of business workhorse PCs that aren't particularly exciting for end users. Sure, the hinge rotates 360 degrees, but that's pretty much it as far as the thrill factor goes. There's no built-in leather case, no touchpad that doubles as a second screen.
