Newegg offers the refurbished ASUS Transformer Book T100TA 10.1" 32GB Windows 8.1 Tablet with Keyboard Dock, model no. T100TA-B1-GR, for $179.99. This $25 mail-in rebate cuts it to $154.99. With free shipping, that's $283 under the lowest total price we could find for a new one, although we saw a refurb for $10 less two weeks ago. It features an Intel Atom Z3740 1.86GHz quad-core processor, 10.1" 1366x768 IPS multi-touch LCD, 2GB RAM, 32GB internal flash storage, 1.2-megapixel front-facing camera, Bluetooth 4.0, 802.11n wireless, microSD card slot, GPS, and Windows 8.1. Rebate expires June 30.
A 90-day warranty applies, although it's unclear who backs it.
