HP Envy Spectre XT vs Acer Aspire S5 vs Apple MacBook Air;Better is......

W.A.Khan,                                                                                                                                                 8/4/2013,                                                                                                                                                                    HP Envy Spectre XT                                                                                                                                                                               Slim and lightweight, the HP Envy Spectre XT is portable, well-built, and easy to use, with a great keyboard.
But, The design doesn't stand out as much as the original Spectre's did, and its battery life won't get you through an entire day. From a premium product, we'd expect a higher screen resolution.
The bottom line: A high-end laptop at a mainstream price, the HP Envy Spectre XT gets much of the look and feel right, with only a few missteps.                                                                                                                                                                                 Specifications

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

But, The Air still has relatively few ports and an expensive starting $999 price for only a 64GB SSD -- and that 11-inch screen feels small for its size.
The bottom line: The new 11-inch MacBook Air is every bit as fast as the 13-inch Air, despite its smaller size, but you'll give up 2 hours of battery life in the bargain.                                                                                                                                      Specifications
