Refurbished laptops from Apple and Hewlett-Packard are relatively inexpensive and, in many cases, virtually new. But it all depends on how you define "new."

Let me begin by saying that I would not recommend a refurbished laptop. That's just my experience, of course. I recognize that others have had positive experiences and that some would swear it's like buying a new computer, just cheaper. But I have purchased two refurbished laptops--one from Apple, another from HP--that were both defective out of the box.

The aesthete buys an Apple. This dig in the latest Mac-attack Microsoft ad contains a kernel of truth.

Here's the essential choice: A Dell with a pedestrian design but all the fixin's or a gorgeous Apple MacBook that doesn't offer quite as much. (Whether the prospective buyer needs a maxed-out laptop is a pertinent question too.)

The Dell paradigm is how many people define practicality, i.e., you get more box for the money. Hewlett-Packard of course falls into this category too.

Samsung expects solid-state drives to reach price parity with hard-disk drives within the next few years amid steep annual price declines in flash memory chips.

Solid-state drives, which use flash memory chips as the storage medium, typically offer much better performance than hard-disk drives. But they cost more. Currently, opting for an SSD instead of a hard-disk drive will add anywhere between $100 and $600 to the cost of a laptop, depending on the capacity of the SSD.

In a phone interview, Brian Beard, flash marketing manager for Samsung Semiconductor, said reaching price parity

Advanced Micro Devices on Monday released low-power and high-performance processors that will find their way into servers from Hewlett-Packard, Dell, Sun Microsystems, and Rackable Systems.

The new server processors are updated versions of AMD's 45-nanometer Shanghai processor.

"When we first came to market, we brought out the standard-power (Shanghai processors) because that's where the bulk of our market is," John Fruehe, the director of business development for server and workstation products at AMD, said in an interview. "As always, more

Dell has issued a system update for a well-publicized problem with Nvidia chips.

The company said Friday it has posted BIOS updates for an Nvidia graphics chip glitch affecting laptop computers. Citing Nvidia information, Dell said the "affected GPUs (graphics processing units) are experiencing higher than expected failure rates causing video problems."

"The issue is a weak die/packaging material set, which may fail with GPU temperature fluctuations. If your GPU fails, you may see intermittent symptoms," the Dell blog said.

Dell said the symptoms include "multiple images, more

Dell will sell you a 128GB solid state drive for an unprecedented $649. But wait. An IDC report claims the performance gap between solid state drives and lower-cost high-performance hard disk drives is not that significant at the system level.

Solid state drives are attracting more scrutiny as they increase in capacity and decrease in price. (Dell's $649 drive is a radical price drop since many drives with half the capacity still sell for more than $700.)

Solid state drives (SSDs) are considered to be generally more power efficient, faster, and in some respects more reliable than hard disk more
