Review Acer Aspire S5-391-73514G25akk Ultrabook


High-end debut. With the 1500 Euros (~$1927) ultrabook Aspire S5,

Very light and stable housing; High performance; Extremely fast SSD combination; Proper input devices; Thunderbolt port; Long battery life

Reflective and qualitatively disappointing display; Moderate Turbo Boost utilization; Noisy under load; No UMTS/LTE or LAN; Limited maintenance capabilities; Very high price

The Aspire's rivals are other high-end ultrabooks such as the Asus UX31A, the Apple MacBook Air 13, the Dell XPS 13 and the Samsung 900X3B/900X3C.

Acer Aspire S5-391-9880


The Acer Aspire S5-391-9880 is a terrific-looking laptop, but it's a mixed bag that doesn't fully justify its premium price.

Robust processor. Uses high-capacity SSD for storage. Includes both Thunderbolt and USB 3.0 ports. Design is thin and light.

MagicFlip I/O Panel is inconvenient, puzzling. No backlight for keyboard. Middling display and sound.

Review: Acer Aspire S5-391-9880


The Aspire S5 is a pricey and powerful entry into the ultrabook market from an unlikely source.

Best ultrabook performance money can buy. Solid audio (courtesy Dolby). Double the storage versus most SSD-equipped ultrabooks

Loud, grinding fan. Small keys, too widely spaced. Arrow keys are so diminutive they’re nearly unusuable. Two USB ports isn’t enough

Acer Aspire S5 Review: A Serious MacBook Air Challenger


If you're looking for an Ultrabook with the superslim good looks of a MacBook Air, enough computing oomph to handle multimedia and general business tasks, plus a good-enough battery life, take a long hard look at the Acer Aspire S5. Especially the...

Exceptionally thin and light, yet powerful ; SSD, superior audio, dual-band Wi-Fi

No ethernet, has bloatware, and is a tad pricey ; SSD limits storage to 256GB

The sleekly designed Acer Aspire S5 Ultrabook poses one of the most credible threats to the MacBook Air we've seen to date.

Acer Aspire S5


With dozens and dozens of Ultrabooks on parade, you'd be forgiven if one skinny laptop with an ultra-low voltage processor started to look like the next. Even so, it's tough to forget the Acer Aspire S5: of all the ultraportables we've seen these last...

Thin, lightweight design ; Insanely fast SSD performance ; One of few PCs with a Thunderbolt port

Poor screen quality for the price ; Drop-down port cover is tedious to use ; Subpar battery life ; Loud fan noise

The S5 is thin and light with blazing disk performance, but this overpriced laptop is marred by serious usability issues, including short battery life and inconvenient port placement.

Acer Aspire S5 Review


Nothing about the S5 justifies the price disparity between it and the Aspire M5, and nothing makes it competitive with other expensive Ultrabooks.

The Acer Aspire S5 is an odd duck. It is extremely thin and provides excellent performance in some areas. We’re unaware of another Ultrabook that can match the Acer Aspire S5’s hard-drive performance, and most Ultrabooks also will be dusted by its Core...

Acer Aspire S5 Review


Let's have a peek at the Acer Aspire S5 , the ultrabook with the mechanical "MagicFlip" dish in the back with ports that whirrs out when you need to plug in and don't need all that pesky space this near-thinnest on the market notebook works with. It's...

In short, this ultrabook is one of if not THE thinnest notebook you’re ever going to want to own, and with a look and feel like this, you’ll have a great time picking one up. The pricing is a bit concerning when compared to other ultrabooks on the...

Acer Aspire S5 review


When Acer introduced the Aspire S5 ultrabook at CES in January, it did so to considerable fanfare. The company said it was the thinnest ultrabook yet, and that it didn't cut corners to get there: the S5 has a Thunderbolt port (good luck finding one on...

Gorgeous design ; Thunderbolt port ; Thin, light ; Solid performance

Very expensive ; MagicFlip is kind of ridiculous ; Gets really hot ; Gaming performance is lacking

Almost the whole package, but $1,399 is too expensive for "almost"

Acer S5-391-9880 review


It was back in January, at CES 2012 , that we first saw the $1,399 13-inch Acer Aspire S5 ultrabook. Of course, if you remember the S5 from CES, you'll recall its most unique feature -- a tiny motorized door at the back of the bottom panel that opens...

The Acer Aspire S5 is an incredibly thin and light ultrabook that hides its ports, including Thunderbolt, behind a clever motorized door.

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.

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.

First generation technology is seldom perfect, and the fruit of Intel's ultrabook initiative was no exception. While vendors came out in force with some fairly impressive pieces of hardware, these first shots at the form factor all came away lacking in...
