Officially, the Consumer Electronics Show runs from Tuesday through Friday, but the show sort of started Sunday, when some companies put their best products on display.

Acer offered up some big announcements in advance of the show, unveiling its new ultrabook, or ultrathin notebook — the Acer Aspire S5 — and, as VentureBeat reported, a new iCloud-like service called AcerCloud.

The notebook, which Acer claims is the thinnest ultrabook on the market at around 0.6 inches, has a 13.3-inch LCD screen and lets users work with the computer using their smartphones. That feature, called the Acer Always Connect, works even when the computer is asleep. The notebook will have the Thunderbolt port that was introduced in March with 2011’s MacBook Pros, a solid-state hard drive for fast booting, an HDMI port, and a USB 3.0 port. And it’s designed to weigh less than 3.1 pounds. The price is yet to be announced.

Acer also introduced a new quad-core tablet, amping up the processing power for commercial tablets by using the Nvidia Tegra 3 to power the 10.1-inch device. The Iconia Tab, sadly, does not yet have a price or a release date.

An ever-increasing number of Internet-connected devices have come to the forefront at CES in recent years, and this year is no different. One of the products that made a splash at this year’s preview was the Body Media exercise and diet tracker, software that personalizes what you can to with the company’s existing armband. Body Media’s FIT coach will track your calories, sleep and activity to help you lose weight.

Another product that drew a lot of attention was the 3M Touch system, a 46-inch display that could be the desk or coffee table of the future. The technology will look familiar to anyone who’s been to a Microsoft store and played around with the company’s Surface technology, but Engadget reported that the 3M Touch prototype impressed demo testers with the responsiveness of its screen. The company told the blog that it will release the product in an educational setting first.
