Lenovo ThinkPad X220T vs Dell Latitude XT3 vs Microsoft Surface Pro:Which one's better?

Lenovo ThinkPad X220T                                                                                                                            The X220 is no thin and light Ultrabook, instead it’s a chunky and reasonably rugged machine. However, this means it can fit in a heck of a lot more connectivity and one of the nicest keyboards on any ultraportable.Classic ThinkPad design in a compact package, amazing battery life, and the latest Intel processors make the Lenovo ThinkPad X220 a standout travel laptop. Intel Core i5 processor outpaces the competition. Largest hard drive in its class. Rugged, ergonomic design. Superb physical keyboard and pointing controls. Melds Windows 7 with a versatile combination of touch and physical controls. The X220 Tablet features a 12.5-inch IPS display (1366 x 768) and ships with optional Gorilla glass for increased ruggedness. The X220 Tablet also boasts a webcam, backlight LED technology, dual microphones and even a fingerprint reader. It includes a software suite and runs Microsoft Windows 7 Professional operating system.On the digitizer side, multi-touch has become pretty much mandatory even though, in all honesty, it doesn't do that much (yet) on a Windows machine. But the X220 has it, and it even works in conjunction with an active pen. Lenovo quotes a battery life of up to 9 hours with the 6-cell battery that's supplied as standard and up to 16 hours with the optional 9-cell battery.
The 1,366 x 768 resolution means the screen can manage 720p high-definition. Needless to say, the screen isn't really suited to watching movies. It's bright enough, but the crispness and colour isn't what you'd find on a dedicated media laptop.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.                                                                                                                                      Specs:                                                                                                                                                         Intel Core i5 2520M processor at 2.5 GHz

Microsoft Surface Pro                                                                                                                                 Making your mind up about the Surface Pro is less about what it is and what it does and more about what you want out of a tablet. As a hybrid PC it's an undeniable compromise - but that's no bad thing.The Microsoft Surface Pro fits a full ultrabook experience in a compact 10-inch tablet. Thanks to the ingenious Type and Touch covers, it offers a comfortable interface and typing experience. The clean, crisp design and sharp 1080p screen rise above the competition.
But, The battery life is disappointing, and more ports would be nice. The 64GB model barely has any free storage. It costs as much as a regular laptop, especially because the cool keyboard cover isn't included by default.
The bottom line: The Surface Pro's gutsy design successfully reinvents the Windows 8 laptop by cramming an ultrabook experience into the body of a 10-inch tablet. Those wanting to go all-in on the tablet experience won't regret buying the Surface Pro, but we're holding out for a future, more polished generation of the device.
