Sony Vaio Pro 13 vs Apple MacBook Pro vs Dell XPS 13:Which is better?

Sony Vaio Pro 13 Touch Ultrabook                                                                                                           Clever design touches, light weight and good looks make the Sony Vaio Pro 13 worth waiting for if you’re out for a practical, portable laptop. If Sony’s battery claims ring true and its battery pack accessory is priced right, this could become one of the best Ultrabooks in town.The Sony Vaio Pro 13 weighs less than 2.4 pounds and uses a fourth-gen Intel Core i5 or i7 processor to deliver long battery life and very good everyday performance. It has an excellent 13.3-inch 1080p touch screen and is competitively priced for its features.the 13.3-inch Full HD 1,920 x 1,080 display is clearly the true star of the show. It’s immensely vibrant and bright, which makes it great for watching high-definition films and video, and the touchscreen is responsive and adds a new dimension to the Windows 8 interface.Battery life wasn’t quite what we were hoping for either. Sony claims battery life of up to seven hours – which can be increased to 18 hours with an optional battery pack – and we did get a respectable six hours and 20 minutes out of it when streaming video from BBC iPlayer.
But, The Pro 13, like its competition, has a nonremovable battery (though you can add an external battery), few ports and connections, and integrated graphics only. Memory maxes out at 8GB.
The bottom line: For those who want an excellent ultraportable laptop with more than just the latest Intel processors, the Sony Vaio Pro 13 Touch is it.                                                                                               Specifications

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
