HP unveils the Pavilion dv4, Envy 14 with Sandy Bridge, and a redesigned Mini 210

With a Sandy Bridge refresh, a new 14-inch mainstream laptop, and a redesigned netbook, HP's latest crop of consumer systems offers a little something for everyone. First up, there's the 14-inch Pavilion dv4 (not to be confused with the metal-clad dm4), which bears the same Imprint finish and CoolSensetechnology as its siblings and ushers in a striking cobalt blue color option, as you can see in the photo above. Look for it on May 18 with a starting price of $600.

Then there's the revamped Mini 210, which swaps last year's not-too-glossy plastic lid for candy-colored lids, and adds a seamless touchpad, edge-to-edge 10.1-inch display, and a flush six-cell battery promising up to 8.8 hours of battery life -- an upgrade over last year's standard four-cell. Spec-wise, nothing has changed from the current 210, except for the addition of Beats Audio, something you'll find across HP's notebook lineup. It'll be available on June 15 and cost $300 for the charcoal version -- alas, you'll have to pony up $330 for one of the punchier colors. For now, be sure to check out our video hands-on.

Lastly, HP did the predictable and refreshed the high-end Envy 14 with Sandy Bridge CPU options and USB 3.0. It also promises an improved touch experience -- something we bemoaned in our review last year -- with a trackpad that uses optical sensors to analyze your multitouch gestures. That will go on sale June 15 for $1,000 and up.

Manual for Alienware M11x with Sandy Bridge confirms NVIDIA GT540M graphics

If the previous Alienware M11x R3 spec leak got you all giddy, then we have some good news for you: according to a manual dug up by one of our eagle-eyed readers, it appears that this year's M11x refresh will indeed be coming with second-gen Core i5 ULV and Core i7 ULV options, along with a faster DDR3 bus (1333MHz instead of 800MHz), a higher-res webcam (2MP instead of 1.3MP), an HD TrueLife LCD, and optional 3G / 4G mobile broadband. But of course, the real meat on this laptop is its graphics card, which turns out to be an NVIDIA GeForce GT540M with either 1Gb or 2GB of dedicated memory -- not bad for a laptop of this size. Unsurprisingly, no dates or prices are mentioned here, but given the early start of inventory clearance, it shouldn't be long before Round Rock reveals all. Dell (ZIP)

Scientist cooks up adjustable strength metals

As you may know, crafting a katana is a delicate process that involves carefully constructing a razor-sharp high-carbon edge around a soft shock-absorbent core. One day though, smiths and forging fires could be replaced by electrode-wielding mad-scientists, with the technology to selectively harden and soften metal at will. At least that's what we envisioned when we read about Jörg Weißmüller's breakthrough research in the field of nanomaterials. The German scientist discovered that by placing precious metals in acid he could create tiny ducts through corrosion. Once those channels are flooded with a conductive liquid, electrical currents can be used to harden the material and, if you change your mind about the brittle results, the effect can easily be reversed to make it soft again. The tech could eventually lead to self-healing vehicle armor or scratch-resistant cellphones -- but, really, we just want to zap our way to a high-quality samurai sword. Physorg

Commodore USA puts the new C64 up for pre-sales, unveils far-less-retrotastic VIC-Slim

Desktops Commodore USA puts the new C64 up for pre-sales, unveils far-less-retrotastic VIC-Slim By Sean Hollister posted Apr 6th 2011 8:43PM Now that Commodore USA has sufficiently piqued your curiosity with a revamped Commodore 64 prototype, it's ready to capitalize on the idea. Quite literally, we might add. $595 buys you the basic basic model with an 1.8GHz dual-core Intel Atom D525 chip, NVIDIA ION 2 graphics, 2GB of RAM and a 160GB hard drive -- which it promises to deliver by "early June" -- with hundred-dollar increments adding premium features like an additional 2GB of memory, a Blu-Ray drive, up to 1TB of storage, 802.11 b/g/n WiFi and Bluetooth. However, if you're simply looking for a compact keyboard computer (rather than reliving 80's nostalgia) there's another option on tap -- a likely rebadged thin wedge of a machine that Commodore's...
