HP Split x2 The HP Split x2 allows it to be used both as a tablet that as laptop, thanks to the base detachable.HP's latest version, called the Split x2, is a bold reworking, moving more firmly into the laptop category, with a thin, 13-inch body and hardware closer to what you'd find in a full-time laptop,this HP convertible computer combines the best of both worlds for an extraordinary touch-screen experience. With a bright LED display and lightweight portability, it is a great choice for an on-the-go student or business professional.Unlike the Envy X2, the Split X2 runs the full 64-bit version of Windows 8. The Split X2 also has a neat party trick in the form of its dual storage solution. Inside the main display, which detaches to become a tablet, is a 64GB SSD; inside the keyboard part is a 500GB hard disk. This means you've got plenty of storage space, although you need to make sure you've copied files to the SSD if you want them available in tablet mode.HP has equipped the Split x2 with a capable specification. The Core i3-4010Y is the first Haswell- generation Core i3 CPU we’ve encountered, and while it lacks the Turbo Boost of more upmarket CPUs, it’s powerful enough for most purposes.The HP ships with a compact 45 watt laptop style charger. The tablet and dock have 3 cell batteries and HP claims up to 10 hours of use time for the Haswell models. Specifications Dual-core processor fourth-generation Intel Core i3-4010Y 1.3 GHz with 3 MB L3 cache.

Price:$799 VS Microsoft Surface Pro 2 The Surface Pro 2's display may not have received an upgrade, but then it didn't need one. It's still a fine IPS panel that helps bring Windows 8.1's colorful and vibrant nature to life. The tablet itself is easier to use thanks to improved keyboard covers - even the Touch Cover 2 will prove more than adequate for most this time around.The Microsoft Surface Pro 2 is a faster, longer-battery-life version of the original model, upgraded with a current-gen Haswell processor. The keyboard cover is also improved with backlit keys, and is among the best tablet accessories ever devised.The Surface Pro 2 is a very tough product to judge, which is what makes it interesting. The good news is Microsoft has sorted out the most serious issue with the first version: the battery life. At around eight hours, the Surface Pro 2 mixes it with the Ultrabooks like the Samsung Ativ Book 9 Plus and Sony VAIO Pro 13, even if it still falls a little short of 'tablet class' battery life.
But, The Surface Pro 2 remains stubbornly thick and heavy compared with some sleeker competitors. The base 64GB version may leave you starved for storage, and the keyboard cover, practically required, should be included instead of sold separately.
The bottom line: Microsoft's subtly updated Windows 8.1 tablet feels more like Surface Pro 1.5 -- improved battery life and better accessories make it a worthwhile (albeit pricey) laptop replacement, but it's still not an iPad-level category killer. Specifications

Weight2 lbs Price $899 VS Asus Taichi 21 The Asus Taichi 21 offers a clever implementation of a dual-screen design in a slim Core i7 chassis.It features dual 11.6" IPS displays with 16:9 aspect ratios and Full HD 1920 x 1080 native resolutions, thanks to the integrated Intel HD Graphics 4000. The main screen inside the lid is a normal laptop display while the outer lid features a secondary touchscreen display. Both screens can be used independently of each other so two people can use them at the same time.
But, Only one of the screens is touch-enabled, which feels like a major oversight. There are probably only a handful of situations where you'd need an outward-facing display.Tablet Mode is on par with this, lasting for 2 hours and 27 minutes. The Taichi is greedier in Dual-Screen Mode, lasting 1 hour and 48 minutes. That last score isn’t too bad considering both displays are on, and screens are one of the biggest battery hogs on a laptop.
The bottom line: More of a clever proof-of-concept than a practical product, the Asus Taichi still delivers on its basic promise, combining two displays for a unique take on the laptop/tablet/hybrid genre. Specifications
