It weighs 1.76 lbs., which is close to the weight of the Samsung Galaxy Note Pro 12.2 running a mobile OS with no fan. It has a light silver magnesium alloy casing and is just 0.36' thick, which is pretty impressive for a machine with an Intel Core CPU and fan inside. This is the lightest and skinniest Surface Pro yet, despite the significantly larger 12' display (previous models had a 10.6') display. It has front and rear 5MP cameras that are a big step up from previous Surface Pro models. The tablet runs Windows 8.1 Pro 64 bit, has dual band Marvell WiFi 802.11AC and Bluetooth 4.0. As ever, RAM is soldered on board, so you won't be able to upgrade it, even if you're up to the advanced surgery required to access internals.

Note that the Core i5 models are available now, but the Core i3 and i7 models won't be available until August 1. As ever, upgrading and even opening Surface Pro is a trial, so if you want more RAM or a larger SSD, opt for Microsoft's 8 gigs of DDR3 RAM model with a 256 gig SSD or the Core i7 with a 512 gig SSD. Today we take a first look at the $999 Surface Pro 3 with the 4th generation Intel Core i5 ULV CPU and Intel HD 4400 graphics, 4 gigs of RAM and a 128 gig SSD. This time, Microsoft ups the ante with a more mainstream 12' size that might just steal a few buyers who were pondering 12.5' Ultrabooks like the Lenovo ThinkPad Yoga and Dell XPS 12.

It's a power user tablet that's on many folks' wish lists, even if it isn't entirely practical as a laptop replacement, because it's just so darned sexy and cool. In Chief (twitter: Microsoft Surface Pro 3 is the latest in MS' line of tablets with the brains of a laptop. What's Not: Type Cover keyboard not included in price, limited ports on tablet. What's Hot: Stunning thinner and lighter design, lovely display, much improved kickstand, full laptop performance.
