Microsoft stock has crept higher since it sank three months ago on word of its Yahoo bid.

Can Microsoft do it again?

Late last year, investors and analysts were wringing their hands over a tech stock collapse. With the economy starting to slow, investors punished a slew of big techs including Microsoft (MSFT), IBM (IBM) and Hewlett-Packard (HPQ). Not even hot-growth companies like Apple (AAPL) and Research in Motion (RIMM) were spared.

Then Microsoft reported earnings in January, and the sun came out: $6.5 billion in profit for the holiday quarter on sales of $16.4 billion. And best of all, the forecast was bright. “We actually feel very optimistic,” said Microsoft Chief Financial Officer Chris Liddell. “The next six months we feel very good about.”

iPod growth has stalled. The iPhone is basically doing as expected. So in Apple’s financial results, the real surprise was the MacBook Air.

This time, gadgets didn’t save the day for Apple (AAPL). Even after adding a pink iPod nano to its lineup in time for Valentine’s Day, the company sold just 100,000 more iPods in the first three months of this year than it did a year before. iPhone sales came in 26 percent (or 600,000 units) lower than the holiday quarter, which isn’t a great sign.

Pick up HP’s new $500 mini-laptop, and the first thing you notice is the aluminum casing. Though the thing weighs only about 2.5 pounds, what’s striking is how its sleek skin makes it feel solid and professional – not at all what you’d expect from a budget PC.

I’m in a suite at the Palace Hotel in San Francisco getting a first look at Hewlett-Packard’s (HPQ) latest machine, which the company hopes will help it steal share from Dell (DELL) and Apple (AAPL) in the education market. (Each of the three companies has just under 20 percent of the worldwide market.) HP’s development team, I’m told, consulted educators as they designed the 2133 Mini-Note, and as I turn the laptop over in my hands that comes through in little details.

Michael Dell is still struggling to reclaim his company’s former glory, and the latest cutbacks show he still has a long way to go.

Dell (DELL) said Monday that it will close an Austin, Texas plant that makes desktop PCs. It’s just the latest step in a plan management laid out nearly a year ago, in which the company plans to shed 8,300 workers and save $3 billion in costs. The remarkable thing about Dell’s announcement isn’t the simple shuttering of a U.S. manufacturing facility – that sort of thing is happening across the country every day. It’s how precipitously Dell has fallen.

While munching on a reuben at Birk’s, a steakhouse in Silicon Valley, Seagate (STX) CEO Bill Watkins is explaining why he’s not too worried about a these trendy new laptops that have everything but a hard drive.

On the surface, this would seem to be a big problem. Seagate, after all, is the world’s largest hard drive maker with expected sales of more than $3 billion this quarter – so Watkins likes to see his wares go into more gadgets, not fewer. It’s easy to see why he tends not to favor devices like Lenovo’s sleek ThinkPad X300, which is winning raves for its light weight and silent operation, and its 64-gigabyte flash storage drive.

HP Chief Strategy and Technology Officer Shane Robison says the reorganization of HP Labs should speed innovation and eventually boost profit margins. Image: HP

Now that it’s an undisputed turnaround story, Hewlett-Packard (HPQ) is looking for ways to fuel long-term growth. An important piece of its plan is HP Labs, a group of 600 top-flight researchers who work to develop breakthrough technologies. To better position HP Labs as a growth engine, the company announced Thursday that it will refocus its efforts on five areas: Information explosion, dynamic cloud services, content transformation, intelligent infrastructure and sustainability.

I sat down with HP strategy and technology chief Shane Robison to talk about the research shift, and what it means for the company. Below is an edited transcript of our chat.

Memory prices are bruising profit margins, but CEO Paul Otellini says the chip giant can still thrive.

Facing flagging profit margins and a skeptical Wall Street, Intel (INTC) CEO Paul Otellini hosted investors at the company’s Silicon Valley headquarters Wednesday. His message: Despite a weak U.S. economy and an ugly memory market, the Internet boom will supercharge revenues at the world’s largest chipmaker.

“We essentially think we can triple the market for our products,” Otellini told a gathering of financial analysts. “And this isn’t assuming that we have a full run of every market; it’s assuming we have a moderate view of success.”

But Intel’s growth story is a tougher sell today than it was a few months ago, which helps explain why the company took the unusual step of hosting investors at its Santa Clara headquarters instead of doing the event in New York as usual. And the tough sell is not just an issue for Intel; since November, when it became clear that the U.S. subprime mortgage crisis could tip the economy into recession, the tech industry in general has been hit hard. Stocks like Intel and Apple (AAPL) that were investor darlings in 2007 have suffered gut-wrenching losses; Intel has shed more than $35 billion in market capitalization, a quarter of its value, since December.

Can Apple regain its status as a Wall Street darling?

So far 2008 has not been kind to the technology trendsetter. With U.S. iPod sales slowing and iPhone hype fading, investors have been seized by worries that the crew in Cupertino isn’t much of a growth story anymore. The stock has fallen 40 percent from its recent highs, losing some $50 billion in market value –and it isn’t clear what could turn things around.

It does seem certain that major relief won’t come from Apple’s (AAPL) newest products. This week’s update of the MacBook laptop line adds speed and memory, but no breathtaking design touches. The super-slim but pricey MacBook Air laptop that CEO Steve Jobs unveiled in January has met with mixed reviews, and won’t provide enough of a boost to make up for the iPod slowdown. And Apple TV, the second incarnation of Apple’s failed attempt to bring digital downloads to the television, doesn’t seem to be attracting an iPod-like following either; on Amazon (AMZN), it’s about as popular as a niche backup hard drive.

So where will Apple go for a sales boost to lift its stock? Perhaps overseas.

Even as U.S. tech spending slows, the market for high-tech gear and the opportunity for Apple to grow, is rapidly expanding in Europe and Asia. To wit: Hewlett-Packard (HPQ) CEO Mark Hurd noted last week that emerging markets accounted for nearly half of the industry’s PC shipments at the end of 2007, and well over half of the growth.

Hoping that Microsoft would clarify how a spending slowdown might hurt the tech industry? Then you were out of luck Thursday.

When the software giant offered its strong earnings numbers, it had nothing but happy news to offer. Thanks largely to stronger-than-expected global PC sales, Microsoft (MSFT) reported $6.48 billion in profit for the holiday quarter on sales of $16.37 billion, beating analyst estimates.

Apple reported earnings that beat analyst estimates on strong sales of iMacs, laptops and iPhones. But its cautious outlook led investors to slam the stock Wednesday morning, and take much of the Nasdaq down with it.

Why?
