Nikon's 1080p CoolPix P100 superzoom up for pre-order, shipping soon.

The compact superzoom party is the place to be, and while Nikon's P100 may not be the most slinky model at soiree, it's got a great personality with its 26x zoom lens, backside-illuminated sensor, HDR functionality, and the ability to shoot H.264 video at 1080p. It's also newly available at a few different retailers for you to put your money where your mouth is, most sites listing some variation on "shipping soon." Amazon is the only one brazen enough to apply a date, but it's a rather vague and general one: three to five weeks.

Sony's DSC-TX5 is waterproof, freeze-proof, dust-proof, and headed for retail this April

You'll be able to go down to 10 feet under water with the TX5, drop it from a 5-foot height, or explore the tundra at temperatures as low as 14 degrees Fahrenheit (-10 Celsius) without the camera throwing in the towel. So Sony claims anyhow. Other features include a now confirmed 10fps burst mode, a 10.2 megapixel Exmor R CMOS sensor, 4x optical zoom plus optical image stabilization, and a 3-inch touchscreen on the back. The one thing that doesn't make the transition from rumor to reality is the reputed 1080p movie mode -- the TX5 makes do with a still desirable 720p video recording. Sony's also kicking out the DSC-H55 (pictured after the break) today, which will have the same video mode, but adds a 10x optical zoom and a thicker, non-weatherproofed body. Both cams will happily write to Class 4 and above SDHC cards when they debut this April, priced at $350 for the TX5 and $250 for the H55.

HP to undercut iPad price, iPad to undercut Amazon e-books prices,

Today's Apple rumor roundup is brought to you by the word "money." First up is a piece carried by the New York Times citing no less than three people familiar with provisions that would require publishers to discount best seller e-book prices sold on Apple's iPad. In other words, below the $12.99 to $14.99 price dictated by the new agency model -- prices Amazon is being strong-armed into accepting. Apple's prices could be as low as Amazon's previously magical $9.99 price point for some titles just as soon as they hit the New York Times best-seller lists. Discounted hardcover editions could be priced at $12.99 even if they do not hit the best-seller list.

The Wall Street Journal, meanwhile, has a pair of sources saying that HP will be meeting with its US and Taiwanese partners to "tweak prices and features" on its upcoming Slate. The move is meant to capitalize on a recent uptick in tablet interest with hopes of undercutting the $629 price of the similarly spec'd 3G-enabled iPad. Although it was introduced before the iPad, HP deliberatly held back on announcing a ship date or pricing so that it could tweak the Slate accordingly.

Also noteworthy is renewed attention given to Microsoft's Courier. The WSJ says that Microsoft continues work on its two-screen Courier tablet at its Alchemy Ventures incubation laboratory in Seattle. However, it's still unclear whether Microsoft will launch the device.
