Lenovo ThinkPad X220 vs Apple MacBook Pro vs Dell XPS 13:Who is the boss?

Lenovo ThinkPad X220 Tablet                                                                                                                 The ThinkPad X220 Tablet is Lenovo’s greatest convertible laptop. This Windows 7 tablet features a 12.5-inch display, Wacom digitizer, and Intel’s new Sandy Bridge processor. Classic ThinkPad design in a compact package, amazing battery life, and the latest Intel processors make the Lenovo ThinkPad X220 a standout travel laptop. The physical keyboard on the ThinkPad X220 tablet is an industry best, providing one of the most comfortable typing experiences of any laptop. It's also spill-resistant, designed to survive up to 4 ounces of liquid spilled directly onto the keyboard. In addition to the touchscreen, you also have two other pointing devices: Lenovo's signature red pointing stick and a revamped touchpad, which incorporates a second pair of mouse buttons into the touchpad. That touchpad also supports the same gesture controls available on the touchscreen, including Lenovo's own SimpleTap user interface. The ThinkPad X220t is available with two different IPS screens. Both have a resolution of 1366x768 pixels and consequently a dot density of 125 dpi, as well as an LED backlight that allegedly supplies a brightness of 300 cd/m2 (300 nits). The gorilla glass screen, available for an extra charge, is described as an outdoor display without multi-touch support.
but,The keyboard is an old-fashioned layout that looks a world away from the sleek black isolation-style keys seen on an HP Envy 17 or Macbook Pro. Screen rotates only 180 degrees in one direction. Gets a bit hot when stressed.
The touch-pad-pointing-stick combo remains an awkward compromise, and as with most ThinkPads you're paying a hefty premium for the sturdy case and business-friendly software.
THE BOTTOM LINE For a business laptop, this is the gold standard. Everyday users will want to look elsewhere, but the ThinkPad X220 is one of the best choices for the business executive. The Lenovo ThinkPad X220 packs in a new Intel Core i5 CPU and can run all day (depending on how you use it). With a 12.5-inch display, it's just a bit smaller than a 13-inch laptop, and it feels like an excellent compromise for frequent travelers.                                                                                                                                       Key Features: Convertible tablet laptop; 12.5in, 1,366x768 IPS swivel screen; Capacitive touch and Wacom digitizer input; Nearly seven hours battery life, 13 hours with slice; Core i5-2520M Sandy Bridge CPU

Price:$1299                                                                                                                                               VS                                                                                                                                                         Apple MacBook Pro                                                                                                                                   The screen is very good, with rich, vibrant colours and great viewing angles, and although not as light and thin as a MacBook Air, the 13-inch MacBook Pro is very portable. The new 13-inch MacBook Pro has a faster third-gen Intel Core i5 processor, and USB 3.0 ports.
But, There's no opportunity to pick a faster processor, for example. It's a pity the entry-level model only uses a Core i5 too, instead of the more powerful Core i7 processors used in the rest of the MacBook Pro range. Not much else has changed: the price, battery life, and older, thicker appearance, however well designed, remain the same.
The bottom line :The 13-inch MacBook Pro is ideal for those who need a little more configurability and storage than the MacBook Air can offer, but also need a very portable machine. While the 13-inch MacBook Pro remains a well-built laptop, it's fallen behind the MacBook Air and Retina Display MacBook Pro in design, lacks higher-end upgrades, and feels too expensive compared with the competition.                 Specifications

It has a usable, backlit keyboard and decent battery life. While it loses points for a low-end display, its $999 price point makes it a reasonable purchase as a more powerful go-anywhere computer to replace your aging netbook.The display is a full-HD panel (1920 x 1080) that features a 800:1 contrast ratio with an optional touch screen for navigating Windows 8.1's UI and apps.This is one area the XPS 13 falls short; it has just two USB ports, a headphone/microphone combo jack and DisplayPort video out. I’m chiefly disappointed in the lack of a media card reader. On the other hand, one nice feature is the inclusion of a battery status indicator which lets you check the amount of battery power you have left even if the laptop is powered off. All picture descriptions are shown from left to right.The Dell XPS 13 has a sharp new 1080p display, updated Intel processors, and the same sleek design as before.
But, Few ports; a high price; no touch-screen option.
The bottom line: Attractive and compact, the new Dell XPS 13 ultrabook isn't that much different from last year's model, aside from new processors and a higher-res non-touch screen.                                             Specifications

Lenovo ThinkPad X1 Carbon vs HP EliteBook Folio 9470m vs Apple MacBook Air:Who is the best?

Lenovo ThinkPad X1 Carbon                                                                                                                        I t's the excellent power management, Incredibly light for a 14-inch laptop, the Lenovo ThinkPad X1 Carbon is ruggedly built, and has a better keyboard than any ultrabook-style laptop, even Apple's MacBook Air. Despite packing a middle-of-the-road Intel Core i5 processor, the Lenovo ThinkPad X1 Carbon stormed our benchmark tests. The score of 9601 in our Cinebench test puts it on par with many Intel Core i7 laptops we've seen, which shows that Lenovo has chosen the very best chip on offer. In real terms this means that any modern program is fair game for the Lenovo ThinkPad X1 Carbon, and you could multitask even the most demanding software - be it bespoke business packages or classic applications such as Photoshop or Microsoft Office.Graphics capability isn't so hot, since the responsibility for 3D is left to the onboard

Microsoft Surface Pro 3 vs HP Envy x2 13t vs Samsung Galaxy Note Pro 12.2:Winner is..........................

Microsoft Surface Pro 3                                                                                                                            Microsoft might not be the first company to break into 2-in-1 laptop, but it's one of the few to get it right. The first Surface was a suave new device that worked both as a laptop and tablet. Thanks to an ergonomic kickstand and excellent magnetic keyboard, it easy to use whether you're at a desk or even laying down. The Surface Pro 3 is thinner and lighter than the previous two versions, despite having a larger 12-inch display and higher screen resolution. A new kickstand makes it easier to set up and use, and the keyboard cover remains a best-in-class example. The Surface Pro 3 is now optimized for a digital pen, which is included.       Performance                                                                                                                                            Despite its remarkably slim and light frame
