Best Buy offers the refurbished 3.1-lb., 0.6"-thick Lenovo IdeaPad Yoga 2 Pro Haswell Core i7 1.8GHz 13.3" Convertible Touchscreen Laptop in Silver Gray, model no. 59RF0580, for $999.99 with free shipping. That's $600 under last week's mention of a new Yoga 2 Pro with this processor and 8GB RAM (with twice the hard drive space) and the best price we've seen for a Yoga 2 Pro with this processor. (It's also $300 under the best price we could for a similarly-configured new Yoga Pro 2 and one of the rare times we've seen a discounted one with 8GB RAM.) This laptop converts into a touchscreen tablet and features an Intel Core i7-4500U 1.8GHz Haswell dual-core processor, 13.3" 3200x1800 touchscreen LCD, 8GB RAM, 256GB SSD, 802.11n wireless, Bluetooth 4.0, 4-cell battery, and Windows 8.1 Pro 64-bit.
A 1-year warranty applies, but it's unclear who backs it.
There's a less expensive way, and then there's the way that works for you. The two may not be the same.
