Shopokey News: “It will, for example, help us to understand how the molecular geometry changes if we change the charge of the molecule,” Meyer said. “What we want is an atomic/molecular level understanding of these processes.”
Fully understanding molecules for basic chip research could be 10 to 20 years away, Meyer said.
Earlier this month, IBM(IBM ThinkPad A21 battery) made a research breakthrough when researchers said they were experimenting with the use of DNA — one of the body’s building blocks — as a way to create tiny circuits that could form the basis of smaller, more powerful computer chips.
But Miller pointed out that lithium-ion technology could still reach a plateau, beyond which it would be necessary to move on with more promising chemical combinations (see Green Light post).
Elton Cairns, a chemical engineering professor with the University of California Berkeley, said that lithium-sulfur Aspire 3000 batteries could offer a next step forward. Lithium-sulfur cells have a theoretical potential to deliver about 2,600 watt-hours per kilogram, versus lithium-ion’s potential of 585 watt-hours per kilogram, he said.
Measuring 13.2 by 9.4 by 1.5 inches and weighing 6 pounds, this laptop is no ultraportable. Much of its heft is due to its 12-cell battery, which sits below the rig, propping up the unit at a more ergonomic angle and delivering good PA3248U-1BAS battery life (just over 6 hours in our PC World Test Center tests, well above the average of 4 hours we get with all-purpose laptops though far short of the outstanding 8-hour battery life turned in by the $1419 Lenovo ThinkPad T400).
“This is just money-grabbing from Apple(MacBook Pro 17″ MA092 battery ),” added someone identified as “thejadedmonkey” on the same thread. “My MacBook Pro came with a matte screen, and it was free. Kudos to Apple for bringing back what they had, but why in the world do they have to be so greedy about it?”
With a laptop this large you can generally expect a large keyboard. Personally, I’m a fan of dedicated numberpads if they can fit comfortably, and the 16-inch form factor is about where you start to see them appear. However, Lenovo(ThinkPad R60 0656 battery) has decided to play tricks with our mind here, taking a keyboard you might see in a 14” laptop and literally shoving it towards the very top of the available keyboard space, giving the whole thing a fairly scrunched look. We can understand the lack of a numberpad, as they aren’t terribly common, but were disappointed to see shrunken keys (like right shift and tab) with so much available space.
Virtual keyboards that appear on touch screens (Apple’s iPhone, Samsung’s Omnia…) have a slow response time and therefore are inadequate for long text typing. Physical keyboards included in pocket devices (Nokia’s communicator series, Sony Ericsson’s Xperia,…) are crammed, cumbersome, sometimes incomplete, lacking some signs or controls.
Despite the disappointment, both sites showed some optimism that the problems would be solved, particularly now that manufacturers have the final “Released to Manufacturing” Windows 7 code to work from. The hope is that by the time Windows 7 ships in October, OEMs will be well underway in producing compatible drivers.Microsoft officials had no direct comment on the reviews except to point to Windows 7 documentation the company has made available to device driver developers.
