I spent less on an Acer Aspire v5-171 last year.
Better i5 (3337U) than the Surface Pro, 6GB of RAM, 500GB hard drive, all in a light and compact 11" form factor. (Oh, and FYI, the Radeon HD 8400 graphics are decidedly low-end; the Intel HD 4000 in the Aspire performs better.)
None of these three devices is a performance device, which is why I might buy a new machine this year -- but it'll have to be better than the Surface Pro 2 at a lower price. Fortunately, that too is not too hard to find.
