Here's the Dell 11 3000, in between my partners 11" MBA and my 13" rMBP. For $319... well, I think it's pretty damn good. The biggest issue by far is the N3710 CPU which lets it down a bit but you can still do most simple stuff on it. It does lag a bit. I upgraded the included 128GB SSD to the 250GB one I had. It has a 4GB DDR3 RAM SODIMM in a slot. If I had access to an 8GB one to try I certainly would, but I don't want to buy one in case it doesn't work, I can't find any mention of anyone who's tried it. I'm also not sure if 8GB will improve it that much. Essentially I wanted a windows machine I could grab without having to get into Bootcamp or Parallels, and I also wanted an 11" machine without the cost of a MacBook Air.
The speakers are pretty good. The screen isn't great but it's not bad for the price. I installed ITunes and that runs fine though does start a bit slowly I have actually still got my library on a 128GB MicroSD. The Micro SD slot is spring loaded something I wish all the Mac's had.
If you just want a small machine to cart around that you can upgrade the storage on, then this certainly isn't the worst one you could buy, specially at the price.
Now I have to read up on my hackintoshing and see if there's any chance it might run, but I'm not optimistic
