Acer opted not to play favorites with its newest batch of all-in-one (AIO) PCs, offering up both an Intel-based (Aspire AZ5700) and AMD-based (Aspire 3100) setup.

The Z3100-U3072 sports a 21.5-inch LCD and a redesigned look Acer describes as "clean." There's an AMD Athlon II 170u (2.0GHz) processor inside, as well as 3GB of DDR3 memory, a 500GB hard drive, Nvidia GeForce 9200 graphics, built-in 5.1 audio, Gigabit LAN, Wireless-N, HDMI, and half a dozen USB 2.0 ports. This one's available now for $600.

Acer saved the stronger components for its 23-inch Aspire AZ5700, which comes built around an Intel Core i5 650 (3.2GHz) processor and Intel HD graphics. There's a TV tuner inside along with an IR blaster port on the outside. Other upgrades include 4GB of DDR3 memory and a 1TB hard drive. This one's also available now, but for $1,100.

Depending on the size of your home, a professional security system may not come cheap. And once you're finished paying for the hardware, there's the monthly fee to contend with. Swann Security has another, less expensive option.

If you can do without the "high-priced hassle of professionally monitored systems" and are willing to bank on loud sirens fending off would-be crooks, then you might be interested in Swann Security's new Home Series Alarm range. The Home Series Alarm Range is an entire line of window, door, and general motion detection alarms that can be used by themselves or in conjunction with a Swann home surveillance solution.

Each alarm emits a 110db+ siren when activated and run as low as $10. The basic Window Alarm, for example, costs a single Hamilton and comes with a self-adhesive pad for tool-less installation. If the built-in sensor detects the vibration of a window during a forced entry, the alarm goes off.

There are several options available, including a $30 wireless ceiling alarm with 360-degree monitoring up to 9 feet. For the full rundown, see here.

Motorola would have you believe its new Oasis behind-the-ear Bluetooth headset is the "most comfortable and lightest" around, and while we can't back that claim without having first tested it, Engadget at least seems to agree.

The funky-looking earpiece sports a rotating boom mic and a lightweight battery that tucks behind your ear. Motorola says it's good for up to 6 hours of talk time, or up to 7 days of standby time.

Other features include echo cancellation, advanced voice prompts, and noise cancellation capable of suppressing wind to 12mph.

The Motorola Oasis goes on sale October 3 for $80.

Acer today is launching a new a lineup of Aspire notebooks geared for entertainment and productivity, including the 3D-ready Aspire 5745DG.

The Aspire 5745DG sports a 15.6-inch 120Hz LCD screen with a 1366x768 resolution and adds Nvidia's 3D Vision technology, which consists of a pair of 3D shutter glasses with a built-in IR receiver. Other features include an Intel Core i5 processor, Nvidia GeForce GT 420M graphics, 500GB hard drive, four USB 2.0 ports, 802.11 a/b/g/n Wi-Fi, media card reader, 1.3MP webcam, and a 9-cell battery.

Also among the handful of new notebooks are three non-3D models, the Aspire AS5642G, AS5745, an AS7745. These range in size from 15.6 inches to 17.3 inches (1600x900) and are powered by Intel's Core i3/i5/i7 processors. All four models include Nvidia's Optimus technology.

Pricing start out at $650, with the 3D-ready AS5745DG available in late October for $1,000.
