I've been seriously considering getting a Chromebook as a second general purpose device for my wife. She's always on my home desktop doing facebook, gmail, pinterest, etc. I also have an iPad, and the number one thing I like about it is the high resolution. I use it mostly for reading, maybe a game now and then, and it's hard to go back to reading text on a regular computer screen after using it for a while. I think a higher res screen would be great.
The samsung one looks nice, but I'm kind of leaning towards the Acer model. From the reviews I've read it is faster, and you can easily swap in 4gb memory and a big ssd.
