Not sure if this helps at all, but I recently had the chance to play with an ATIV Book 7 (Intel i7 model), and in some ways was thoroughly impressed, in others barely.
First and foremost, lets get W8 out of the way, I detest W8 in ways that most people cannot imagine, if your the same head straight to ninite.com (no www.) and install all of your favourite apps, utilities, anti-malware, antivirus etc, and also tick the box that says "classic start", wiith this and a re-boot you can make the laptop actually usable. However I had a touchscreen that cannot (to my knowledge be disabled).
Another point (only if you detest W8), disable the "side-swipe" touchpad options as they will drive you mad when you do anything with the touch-pad and don't start inside the edges of the pad, whoever thought this was a good idea should have their balls cut off while they are conscious and fed to them
The screen on this £1,000 model was 1920x1080 and on a 13.3" screen too small for someone who loves lots of pixels, setting the "Display" to 125% fixed this, although many people may want to go to 150% (model and resolution to be taken into account). The screen was pretty damned good although a little over-bright, it had wide viewing angles and looked very crisp.
Apart from W8 on the laptop my main complaint was the SSD, My original 64GB Sandforce SSD totally outperformed this laptop in every way.... saying this, I cant compare the CPU performance difference between this laptops i7 and at the time my desktops Quad core AMD 3ish GHz chip.... again, I was actually surprised and saddened at how slow this laptop was to do ordinary disk-based tasks such as open a browser (8GB of RAM wasn't the issue) so the SSD must have been lame, I sadly never got the chance to benchmark the SSD.
Due to the size of the laptop, there was no 1.8" or 2.5" HDD option and a DVD drive was out of the question, so all other forms of storage must be USB, the line between a "chromebook" and an "ultrabook" is thinning fast due to cost and lack of storage on the ultrabook.
I would love to see a direct comparison of a comparably priced "Chromebook" and "Ultrabook". I have nothing against "Ultrabooks" except what I have listed above, and have not yet had the chance to actually use a "Chromebook" so I have no dog in this race.
