The Samsung Series 7 All-in-one

The product: 
Among other 23-inch Windows 8 all-in-ones, the Samsung Series 7 is one of the most affordable, without sacrificing too much in terms of its core features. Other all-in-ones offer some more intriguing features if you're willing to spend just $100 or $200 more, but if your needs are simple, and/or if you have a hard budget limit, the Samsung Series 7 offers perfectly serviceable

The Lenovo IdeaPad Yoga 13

What you should know: 
Despite the excellence of the hinge design, the Yoga 13 does have one design flaw. Because it uses the same 16:9 aspect ratio that is common on Windows PCs, the 13-inch screen becomes awkwardly long when held in portrait mode. Were it an 11-inch system, like the Sony VAIO Duo 11, the size would be just right. Measuring 0.66 by 13.4 by 8.85 inches (HWD), the Yoga 13 is well sized as an ultrabook, but it's too big for comfortable tablet use. It's also a bit heavy (3.4 pounds), just a little heavier than the 3.3-pound Dell XPS 12.
What it offers: 
The Lenovo IdeaPad Yoga 13 is a solid ultrabook, but as a tablet, it's a little too big for comfort. Otherwise, the Yoga 13 has the best hybrid design we've seen so far.
The advantage: 
Solid Windows 8 ultrabook. Folds back for tablet and stand modes. Excellent keyboard. Speedy performance thanks to Intel Core i5-3317U processor and 128GB solid-state drive.
The unfavorable: 
Too large and heavy for comfort as a tablet.
The price:
$ 999.00

The Sony Vaio Tap 20

The advantage: 

By slapping a battery inside a 20-inch touch-screen all-in-one to make the Sony Vaio Tap 20, the company has given birth to a new PC category with great potential in tech-savvy homes.
The unfavorable: 

The touch screen has some frustrating drag, and Sony made a few missteps among some otherwise reasonable sacrifices for portability and price.
The offer: 

A compelling experiment in tablet-desktop hybridization, the Sony Vaio Tap 20 is a great fit for home tech enthusiasts willing to try something new.

The Tap 20 measures 19.75 inches wide, 12.13 inches high, and, at the thickest point of its tapered back panel, 1.5 inches deep. It weighs just under 11.25 pounds.

The 20-inch display makes sense as a way to keep the Tap 20's size and weight down, and in order to manage heat and battery life, Sony chose an ultralow-voltage 1.7GHz Intel Core i5 mobile CPU. The absence of an optical drive is conspicuous, but likely helps keep the Tap 20's thickness in check, and it's not out of keeping with other Windows 8 PCs.

The Acer Aspire M5 and V5 Ultrabooks

The Acer's Aspire M5 and V5 had been unveiled. The Aspire M5 measures under an inch thick, with a clean-lined design, wrapped in an aluminum alloy cover. At 4.6 pounds, the 14-inch M5-481PT comes in on the heavier side of the ultrabook spectrum. A $699, 15.6-inch Aspire M5-581T weighs "about 5 pounds,"
Each laptop has a standard mobile Intel Core i5 CPU, a 500GB mechanical hard drive, and, unlike Lenovo's new optical drive-free laptops, a DVD burner. If all of that sounds uninspired, each system also has a backlit keyboard, as well as a 20GB solid-state drive (SSD) included to speed boot time and improve access time to commonly launched applications

Aspire V5 notebooks run Windows 8 and have Intel Core i3, i5 or i7 processors with Turbo Boost Technology 2.0, 500GB or 750GB hard drives, Intel HD Graphics 4000 and USB 3.0 ports. The 14-inch and 15-inch notebooks also have DVD drives. While they’re not exactly lightweight with each model weighing 3 pounds, 4.63 pounds and 5 pounds.

The Acer Aspire V5 Series notebooks will land U.S. and Canadian retailers on October 26th with pricing starting at $449.99 (11.6-inch), $749.99 (14-inch with touch), $499.99 (15-inch without touch) and $699.99 (15-inch with touch).
