Popup annoyances notwithstanding, Dell delivers a mostly clean desktop experience on the Inspiron 14z. It isn't littered with icons and shortcuts. There's a weather widget in the upper right corner, and Dell's customizable Stage software along the bottom, which you can disable if you prefer.
By default, Inspiron 14z Ultrabooks come with 90 days of phone support and a 1-year hardware warranty. For less critical issues, Dell's included Support Center software helps keep tabs on your system's vitals and allows you to create backup media, check the status of the battery, and other odds and ends.
Windows Mobility Center is a handy utility baked into Windows that doesn't often receive a ton of attention. It's made even more robust by Dell on the Inspiron 14z, giving users quick access a wealth of knobs and dials related to various wireless technologies and audio, as well as the touchpad.
