Acer sent us word that it's expanding its projector line with the U5200, an ultra-short throw model intended for teachers and educators.

"The key features that are most important for schools have now been integrated into the new Acer U5200 projector, such as LAN control, display over USB, and Ultra-Short Throw projection to help create a compelling learning environment," Acer said.

Using an advanced mirror-reflection type of ultra-short throw projection, Acer says the U5200 can display large images even when placed close to the screen. All that's required is a distance of 13cm to produce sharp and accurate images up to 195.6cm (diagonal).

Other features include up to 5000 hours of lamp life (ECO mode), native XGA resolution, 2,500 ANSI Lumens, 1.07 billion displayable colors, IR remote control with laser pointer, and integrated 20W speakers.

The U5200 will be available starting March 1, 2011 for around $1,800.

Several wireless carriers plan to offer Samsung's Galaxy Tab starting in November, but none before T-Mobile, which today announced it will begin selling Samsung's upcoming slate on November 10, 2010.

"Customers want richer, deeper interactions with entertainment and online content through connected, portable mobile broadband devices that are small enough to carry and big enough to share with friends and family," said Jeremy Korst, director of broadband products and services, T-Mobile USA. "T-Mobile’s unique offerings on the Galaxy Tab paired with the power of T-Mobile’s new network allow us to bring a truly differentiated portable entertainment offering to market."

We've covered the Galaxy Tab ad nauseum up to this point so we won't rehash the specs, but will point out that T-Mobile will offer the device starting at $400 with a 2-year service agreement on a qualifying broadband plan. For the sake of comparison, here's how the Galaxy Tab breaks down with other carriers and distributors:

• Sprint: $400 with 2-year data plan, available November 14
• Verizon: $600 outright (no data plan required), November 11
• Best Buy: $500 outright (Wi-Fi only), no announced release date

Talk about ending the week with a bang. HP on Friday announced five point-and-shoot digital cameras and three camcorders, all eight of which are aimed at the mainstream crowd and priced no higher than $199. What's most remarkable about this is that half the new models sport a touchscreen display.

Of particular interest are the V5061u and V5560u camcorders. Both come with 3-inch touchscreen LCD displays and are some of the least expensive touch-enabled camcorders around capable of shooting in 1080p. The V5560 adds 5X optical zoom to the mix and runs $199, while the V5061u is priced at $169.

On the point-and-shoot front, the CW450t ($109) and PW460t ($149) boast 2.7-inch and 3-inch touchscreen displays, respectively, along with a newly designed touch interface for viewing photos with a swipe of a finger. Both also boast 4X optical zoom and support up to 32GB SD/SDHC memory.
