With the wireless radio left on and display panel set to auto-brightness, the Aspire S7-191 (with the 3-cell battery bar attachment) achieved just under 4 hours of a PowerMark balanced productivity and entertainment scenario. This is less than half the advertised 9.5 hours by Acer (we really need an industry standard for battery life measurement) but ahead of the other Ultrabooks that we've tested except the Asus Zenbook Touch UX31A.
At the recent local IT SHOW 2013 event, the Aspire S7-191 retailed at a promotional price of SGD$1698 (Amazon sells it for US$1049, wow the exchange rate disparity), which is pretty mid range in the Ultrabook pricing spectrum.
There are many positives in this 11.6" wonder such as the gorgeous display panel and RAID-0 disk I/O responsiveness, but the lack of system memory (non-upgradable), internal storage and other small niggles makes it hard for us to wholeheartedly recommend it to creative professionals who create content and do more than just watch movies. Still, this is one of our favourite top 3 Ultrabooks from this generation.
The Acer Aspire S7 could have been the Apple Macbook Air killer.
