The coming Windows 8 release is generating a variety of form factors, as computer makers try to take advantage of the new Microsoft Relevant Products/Services operating system's advantages, notably touch. On Monday, Acer released two of its entries in this contest -- all-in-one desktops that are maximized for touch.

The new models feature large displays that, along with wireless mouse and keyboard, are the entire computer. They offer advanced 10-point capacitive touch technology with enhanced gesture recognition, in support of humans' 10 fingers. The slim -- less than 1.4 inches -- high-definition screens are available in 27- and 23-inch sizes, and the display can recline up to 80 degrees for ergonomic variety.

'No Compromise Solution'

A semi-transparent enclosure for the screen houses the hard drive, optical drive and screen, and a VESA mount kit allows an owner to mount the display on the wall. The displays sport 1920x1080 resolution, a 5-millisecond response time and discrete graphics, while Real Sound Lab's CONEQ sound tech offers virtual surround sound.

Frank Chang, Acer America's director of desktop product management, said in a statement that the new products, the 27-inch Aspire 7600U and 23-inch 5600U series, offer "a no-compromise solution for those wanting the power of a desktop in a sleek and elegant chassis."

The 7600U features an Intel Relevant Products/Services Core i5 3210M processor Relevant Products/Services running at 3.1 GHz with 8 GB of memory, discrete Nvidia GT640M graphics, a combo Blu-ray drive/DVD player and two HDMI inputs. The 5600U has an Intel Core i5 3210M processor at 3.1 GHz, up to 8 GB of memory, a SuperMulti optical drive and one HDMI input.

Chang added that the "blend of Windows 8, capacitive touch technology, instant resume functionality and fast processing deliver a superb computing experience" for consumers or students.

Tired Hand Issue?

Acer's Instant On is offered as an option, providing instant-resume functionality in 1.5 seconds. The company said this makes the computer nearly as fast to turn on as a TV.

All-in-ones are joining such form factors as Lenovo's hybrid, convertible tablet/laptop computers as solutions that attempt to take advantage of the touch-with-traditional interface characteristic of Windows 8. But, as the various designs attempt to offer something that satisfies Windows' new potential, there is a looming question: are they form factors that will satisfy buyers?

We asked Michael Gartenberg, research director for Gartner, about whether he expected buyers would welcome Windows 8 all-in-ones.

He noted that various emerging Windows 8 form factors are "designed for touch, but also need to accommodate interaction via mouse and keyboard," if only for applications Relevant Products/Services using the traditional Windows interface.

But, Gartenberg said, it's an open question if a single large screen is all that useful as an everyday computer because, "after awhile, your hand starts to get tired." He pointed out that potential buyers of all-in-ones "aren't going to get onboard with this form factor unless computer makers can tell them not only how this is different, but why it is better."
