I love my Acer CB5-571. It has a Celeron 3205U processor (Octane score of around 14000), 4 GB RAM, full HD 15.6" screen (which has excellent image quality), great keyboard, good speakers. I got it for around $180 refurbished on the Acer eBay store, but you can often find it new for around $220-230 if it's on sale. There's an i5 version which is even faster, but I think it goes for more like $300-400. The CB5 is on the list of Chromebooks that are supposed to get Android app support.
One of the current Chromebook darlings for tech writers is the Acer Chromebook 14, so that's worth checking out as well.
