The Chromebook Pixel is a Core i5 laptop with 4GB of RAM and a 32GB or 64GB of storage. It's also got a crazy-beautiful anodised aluminium case, and Google is making a lot of fuss over the trackpad being specifically coated and designed. According to the first few hands-on articles, the work on the trackpad has paid off - it's quite good.
The real looker here is of course that display - 2570x1700 pixels at 12.85" means a ppi of 239, which is quite insane. It's also touch-enabled, but ChromeOS isn't exactly touch-optimised. Still, my Surface RT has taught me in a few days that even in a non-touch interface, it's just natural to touch stuff, so good on the Pixel for including it. The display is also 3:2, which isn't a widescreen - a bit weird, but it probably makes sense for most webpages.
The price is hefty: it starts at $1299 - which makes me wonder who this thing is for. ChromeOS is not really a full operating system, and still has a long way to go in that regard. Well, maybe it's hackable and we can run Linux-proper or Windows 7 on it.
