Techspot popsted a review on the Acer Aspire TimelineU M5

With the initial fruit of Intel's ultrabook initiative having dropped nearly a year ago, the category is now home to a veritable cornucopia of machines from practically every PC maker. While this has produced some highly attractive products, it has also muddied what was once a clear mission statement.

Ultrabooks were originally pitched as Windows-based competitors to Apple's MacBook Air: thin, light, sexy and speedy with an all-day battery life for less than $1,000 -- a challenging feat to be sure, but one that many companies quickly overcame, including HP with its ~$900 Folio 13.

With another year's worth of engineering and the more efficient Ivy Bridge architecture to work around, it should be even easier for system builders to meet or exceed Intel's guidelines. On paper, the second wave of ultrabooks should be sleeker, faster, cheaper, more portable, and more autonomous.
