Microsoft Store offers the 2.4-lb. Acer Aspire Switch 10 Signature Edition Intel Atom 1.33GHz 10.1" Touchscreen Convertible Laptop, model no. SW5-012-12L7, for $229 with free shipping. That's tied with our expired mention from five days ago and $71 under the lowest total price we could find for a similar model. (We saw it very briefly for $25 less last week.) Designed for use as a notebook or tablet, it features an Intel Atom Z3735F 1.33GHz quad-core processor, 10.1" 1280x800 touchscreen IPS LCD, 2GB RAM, 32GB eMMC, 802.11n wireless, Bluetooth 4.0, webcam, micro HDMI and micro USB (located on the tablet), USB 2.0 (on the keyboard), 2-cell battery, and Windows 8.1 32-bit.
