Top-rated reviews of the week

Want to set up your iPad like a desktop monitor? Want to use your home power lines for an Internet connection? We're all about flexibility this week, as CNET reviewers approve a gadget that brings Bluetooth to older cars, a big-screened ultrabook, and a fitness tracker you can throw in a pocket. Also, in the "surprisingly budget" category, a great TV, audiophile earphones, and a luxury Kia (really).
