Even though it's a tablet/hybrid, I thought I'd point out that the very capable Dell Venue 11 Pro 7140 (64gb/4gb/Core M) is on sale for $300 INCLUDING keyboard at A4C.com (coupon code TECH25). I'm actually considering this myself up against the less powerful Asus T100HA ($300, Cherry Trail Atom), but the lack of a true clamshell keyboard has me second-guessing (which is the main reason I ditched my Surface Pro and my original Surface sits on the kitchen counter 100% of the time (though it does still get a lot of use for casual email/text/security cam/epicurious)... there is at least a clamshell keyboard available for the Venue 11 Pro, but it's relatively pricey ($120 new, $60-$75 on eBay) and it does double the battery life to 15+ hours. If my new employer tries to saddle me with a heft laptop, I'll have to decide between the Venue 11 Pro or the Asus T100HA.
