I picked up an Acer C720 about a year ago that was good enough that I don't even carry around the Mac Air that my company gave me. 2GB RAM, Celeron 2955U haswell processor, 8-9 hour battery life, hdmi/USB3, SD slot, 16GB storage, same video resolution as the HP above. All for US$199 and in a 2lb package.
I thought I'd need more storage, but it's a year later and I haven't used more than about 10GB of the internal storage. One of these days, I'll upgrade it to 32GB or 64GB, but I've just been storing my personal files on either a 64GB SD card or 64GB USB 3.0 fob.
Having something this thinly provisioned running the bloat that is Win 8.1 wouldn't be attractive for me at all, regardless of the price point. However, it's great for ChromeOS and Ubuntu Trusty.
