Lenovo IdeaPad Yoga 13 The 13-inch Lenovo Yoga was one of the first convertible Windows 8 tablet/laptops.Packed into its flexible chassis, the Lenovo Yoga 13 has some tasty specs: its 13-inch IPS screen may not offer a Full HD (1,920 x 1,080) resolution, but at 1,600 x 900 pixels it’s significantly higher than many affordable rivals and offers 10-finger touch. Under the hood, this Yoga can offer up to a Core i7 CPU, up to 8GB of RAM and a 256GB SSD, putting it at the top of the convertible game in terms of power – yet Lenovo still claims battery life of up to eight hours. All that’s lacking is pressure-sensitive stylus support, but as the Core i7 version comes in at under $1,000.00 , that’s easy to forgive.Intel's 1.70 GHz Core i5-3317U, which has two cores capable of delivering four processing threads with bursts up to 2.6GHz, outputs a surprising amount of giddy-up.Upgrading to the faster Core i7-3517U, which runs at 1.90GHz with bursts of up to 3.0GHz and has a 4MB cache vs. the Core i5-3317's 3MB cache, will give you even more CPU kick.The Lenovo IdeaPad Yoga 13 looks as good as any 13-inch ultrabook, with the added attraction of a 360-degree screen and a laptop body that can fold into a tent, stand, or slate.
But, Tablet mode leaves the keyboard exposed, and the Yoga 13 costs more than standard ultrabooks with similar components.
The bottom line: The Lenovo IdeaPad Yoga 13 is a convertible touch-screen laptop/tablet that most importantly doesn't compromise the traditional laptop experience. Specifications

Optical DriveNone Price; $1,000.00 VS Asus Transformer Book TX300 The Asus Transformer Book TX300 is a rare hybrid with a Core i7 CPU, a high-res screen, and smart dual hard drives -- there's an SSD in the tablet half, and a larger hard drive in the keyboard base.The screen is fantastic, as is the overall build quality found across this aluminium-clad laptop. Quality oozes from every panel, and while it's in no way lightweight, the TX300 is thin enough to slip into a bag, although you'll feel it as you walk around.The tablet packs in a 38Whr battery, which gave us pretty good performance in Battery Eater Pro. We managed to get 2 hours and 28 minutes, which roughly translates to about 4-5-hours of real world usage. This is not bad considering we haven’t counted the battery in the dock as well.It runs Windows 8 on an Intel Core processor and also includes four gigabytes of RAM. Long-term storage is provided by 128Gb or 256GB solid state drives. This makes the system both a convertible and an Ultrabook. ASUS claims this is a world first, though that’s not exactly true. Dell and Lenovo have offered convertible Ultrabooks for months.The Asus Transformer Book TX300 is a great example of a hybrid laptop/tablet. Once the screen is attached, it turns into a true laptop with a high-performance processor and an excellent display. And as a tablet it's perfectly honourable.
But, The system is awkwardly top-heavy, and you feel as if you're fighting the touch pad at every turn.
The bottom line: Asus adds a lot of what I've been looking for in a hybrid to the Transformer Book, but no one has yet really nailed the perfect laptop/tablet combo. Specifications

Optical DriveNone Price;$1,454.99 VS Dell XPS 12 The Dell XPS 12 is a thin, powerful, very cleverly designed touch-screen convertible that flips into multiple screen positions.This machine’s key feature is a 12.5-inch touchscreen with a native resolution of 1920 by 1080 pixels that pivots inside its aluminum frame—just as on the original. Open the lid, and you can use the computer as you would any other notebook. You simply push the top front or bottom back of the display to pop it out of its frame, and then flip it over and close it to convert the machine into a tabletThe biggest improvement, though, lies in battery life. The Ivy Bridge version of the XPS 12 provided 5 hours of streaming video, but that figure rose to a 6 hours and 45 minutes when we tested again with the same test.The Dell XPS 12 is one of the most powerful Ultrabooks you'll find. It might be heavy and awkward as a tablet, but when you consider the value that's on offer, with the blistering processor, 8GB of RAM and 256GB SSD drive, there's more than meets the eye..
But, For all the hype about touch and tablets with Windows 8, the XPS 12 still works better as a laptop than as a slate. Its battery life is on the low side.
The bottom line: Dell has revamped its rotating Duo laptop concept into the much-improved XPS 12, but like most convertibles, it makes a better laptop than tablet.
