W.A.Khan, Lenovo ThinkPad X1 Carbon The Lenovo ThinkPad X1 Carbon is a boardroom winner that offers great all-round performance and comfort in a lightweight package.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.
But, For such an expensive laptop, battery life is just so-so. Consumer-friendly options such as HDMI are missing.
The bottom line: The business-oriented Lenovo ThinkPad X1 has a few quirks, but is otherwise a very impressive business-oriented ultrabook with strong crossover potential.

Optical DriveNone Price;$1,424.05 to $1,684.00 VS Acer Aspire S5 The Acer Aspire S5 is an incredibly thin and light ultrabook that hides its ports, including Thunderbolt, behind a clever motorized door.
But, That port door, named the MagicFlip, is a potential problem if it ever breaks down. The keyboard isn't backlit, and battery life could be better.
The bottom line: Even thinner and lighter than a 13-inch MacBook Air, the Acer Aspire S5 is a great example of an ambitious ultrabook, held back by a few flaws and its high price. Specifications

Optical DriveNone Price;$1,399 VS HP Envy TouchSmart Ultrabook 4 The HP Envy TouchSmart Ultrabook 4 has a nice array of ports, including a cleverly designed 10/100 Ethernet port that expands when you push the cable in but stays within Ultrabook height specs when closed.HP's Envy TouchSmart Ultrabook 4 is an attractive ultrabook with a respectable mix of components for its price, a responsive touch screen, and a backlit keyboard.
But, The Envy TouchSmart 4 isn't very configurable, so you can't make it too much more powerful than it already is. It's on the heavy side for an "ultrabook" (if you consider 4.5 pounds heavy). Its touch pad is jumpy at default settings.
The bottom line: The HP Envy TouchSmart Ultrabook 4 is a good gateway to the Windows 8 experience with a responsive touch screen in a traditional laptop body. Specifications
