NeweggFlash offers the refurbished 5.2-lb. Sony VAIO Intel Ivy Bridge Core i5 1.8GHz 15.5" Touchscreen Ultrabook, model no. SVT15114CYS, for $499.99 with free shipping. That's $100 below the lowest total price we could find for a refurb elsewhere. (It's also a really low price for any Sony 16" 1080p touchscreen laptop.) It features an Intel Core i5-3337U 1.8GHz Ivy Bridge dual-core processor, 15.5" 1920x1080 touchscreen LCD, 4GB RAM, 750GB hard drive, 802.11n wireless, Bluetooth, webcam, DVD drive, 6-cell battery, and Windows 8 64-bit.

Note: A 90-day warranty applies, although it's unclear who backs it.
