Nokia is the global cell-phone leader, with sales of 329 million units in 2009. Yet when it comes to feature-packed smartphones in some markets, including the U.S., analysts say Nokia is under threat from rivals Apple, Research In Motion, and Google.

Research In Motion may find that many of its customers are in motion, a survey of more than 1,000 smartphone users suggests. Asked about their next smartphone purchase, 39 percent of 159 RIM BlackBerry users told Crowd Science, an online research firm, that they "definitely or probably" want an Apple iPhone.

Another 34 percent said they would prefer a phone that uses Google's Android operating system. Combined with 38 percent who said they might consider Android, that makes a 72 percent opening for Android, narrowly beating the 68 percent opening for the iPhone.

Microsoft isn't going to let Apple have all the app-store fun. On Monday, the software giant announced more details about Windows Phone 7 Series applications in its online store as it moves to get third-party developers excited about the new platform.

Booting up PCs will be faster with Intel's new 40GB solid-state drive (SSD), the company said Monday. Intel has begun shipping the Intel X25-V Value SATA SSD.

Used in dual-drive notebook configurations or added to a desktop with an existing hard drive, the X25-V can contain the operating system and the user's favorite applications to make startup faster.

Considered a game-changing technology to replace hard drives, SSDs have been replacing traditional magnetic hard drives after they proved to be faster, more reliable, and more energy efficient.

Version 4.0 of the operating system for Apple's iPhone, iPod touch, and the forthcoming iPad will represent a major overhaul of the software and will feature a "full-on solution" to one long-standing gripe about Apple's devices -- their inability to multitask.

At least that is the latest rumor making the rounds, as reported by the AppleInsider blog. The site attributes the report to "people with a proven track record" in predicting Apple's next moves.

With its mind in the clouds and an eye on rival Microsoft, Google on Tuesday launched an online application store for third-party programs that can be integrated with its online Google Apps office suite, with a single log-in and Google's universal navigation. The programs can sync with Gmail and Google's calendar, and use document-sharing features.

With the stakes high in Microsoft's bid to add its search engine to the iPhone, a few words of praise by the software giant's CEO have drawn a considerable amount of attention.

"Apple's done a very nice job that allows people to monetize and commercialize their intellectual property" in the App Store, Microsoft CEO Steve Ballmer told a University of Washington audience last week.

As Internet and television continue to converge, Google is actively testing a new television-programming search service with Dish Network, according to a report in The Wall Street Journal. The service reportedly runs on TV set-top boxes that host Google software and enable viewers to find shows on Dish and video on web sites like YouTube. The Journal cited people familiar with the matter who said the service will allow viewers to personalize a lineup of shows.

Rivals of Microsoft's market-leading Web browser have attracted a flurry of interest since the company, fulfilling a regulatory requirement, started making it easier for European users of its Windows operating system to switch.

Microsoft Corp. has said its new software for smart phones, Windows Phone 7 series, is a "clean break" with the past. Now it's clear just how clean that break is: The new phones, expected late this year, won't run any applications written for older versions of Microsoft's phone software.

In a blog post Thursday, Microsoft executive Charlie Kindel, who handles contact with outside software developers, said that jettisoning support for older applications was necessary to make the new operating system as powerful and user-friendly as possible.
