Aside from games, some of the most popular categories of iOS apps in the iTunes App Store are note-taking apps. Whether you're a student taking notes for class or your workday requires that you take notes in meetings, a handy app that makes it easy to jot things down and organize them can be incredibly useful.

Apple's Pages ($9.99) is probably the most obvious choice here, having been around since the first iPad was launched (now a universal app for iPhone and iPod Touch as well), but there are several third-party apps that offer different features that might be more in tune with your style of note-taking.

This week's iOS apps are all about taking notes. The first is all about taking notes that autosync across all your devices; the second offers a sleek-looking interface with several themes to categorize your notes; and the last is an iPad-only app offering an elegant system for keeping your class and meeting notes organized.… Read more

LCD televisions are the most-desired sets around the globe, but their sales growth is starting to slow, according to a report today from research firm DisplaySearch.

During the first quarter of 2011, over 44.2 million LCD televisions were shipped worldwide, earning the technology 80.1 percent ownership of the overall TV market. Though year-over-year growth was up by 9 percent, DisplaySearch said that rate was "the weakest year over year growth ever for LCD TV, and the only quarter with single-digit growth." By comparison, in the first quarter of 2010, LCD shipments were up 50 percent compared … Read more

Televisions boasting 3D capabilities will be far more popular this year than last, market researcher In-Stat predicts.

According to an In-Stat report released today, 3D TV shipments will be up nearly 500 percent worldwide this year, compared with 2010. In-Stat also predicts that sometime soon all televisions with screen sizes of 40 inches and above will come with 3D functionality.

Biomass used to make biofuels must be carefully sourced, or the biofuels they produce may be no greener than conventional jet fuel.

That's according to a study that was published this week in the online version of Environmental Science and Technology and was conducted by a group of scientists at the Massachusetts Institute of Technology.

For the nearly four-year study, researchers conducted a life cycle analysis on 14 diesel and jet fuel sources made from feedstocks, and identified the key factors that make a difference in whether a biofuel is truly an environmental improvement over conventional jet fuel.

Companies are actively looking for Microsoft Office alternatives such as Google Apps, but so far their interest hasn't dented the productivity suite's dominance, a Forrester Research study released today said.

"Adoption of alternatives relative to Microsoft Office is paltry, but interest remains high, with more than a quarter of companies actively looking at or experimenting with Web-based alternatives," Forrester said in the study. "While the free versions of these programs make it easy for companies to try, concerns over user acceptance and compatibility with Microsoft Office file formats continue to hinder broader deployments."

As Apple and Verizon's quarterly earnings noted, iPhone 4 sales have been brisk. How brisk? A new report put out by the NPD Group earlier today put Apple in third place in U.S. smartphone sales during the first quarter of this year.

Apple came in behind Samsung and LG, but did better than HTC, Motorola, and Research In Motion. During the quarter, NPD says Apple nabbed 14 percent of sales, due in large part to the launch of the iPhone on Verizon's network in February.

"Apple and Verizon had a very successful launch of the iPhone 4, which allowed the iPhone to expand its market share that was previously held back by its prolonged carrier exclusivity with AT&T," said Ross Rubin, NPD's executive director of industry analysis in a statement.

Rubin said some of that growth "came at the expense of the Android OS" even though phones running Google's mobile phone OS made up half of the devices sold in the three months counted.

According to NPD's data, this was the first time Android's overall sales shrunk, going down to 50 percent from 53 percent the previous quarter. RIM's BlackBerry OS share also dropped to 14 percent of sales, down from 19 percent the previous quarter. Eating into those numbers was Apple, with iOS jumping 9 points to rest at 28 percent of smartphone sales, due to combined sales of the iPhone 4 and the iPhone 3GS, both of which NPD includes in the top five sellers. … Read more

Apple frequently touts the number of applications available to iOS users, which now sits north of 350,000. But that number could be in danger of coming in second place to rival Google in just a few months time.

In a new report by market research firm Distimo for the last month of activity on Apple's various App Stores, the BlackBerry App World, GetJar, Google's Android Market, Nokia's Ovi Store, Palm's App Catalog, and Microsoft's Windows Phone 7 Marketplace, the group found Google and Microsoft's efforts to be growing the fastest.

A new study put out by ComScore found that there are more than double the number of iOS users in Europe compared with those on Google's Android platform.

The study, which tracked residents in the U.K., Germany, France, Spain, and Italy, pegs combined iOS users at 28.9 million, with Android coming in at 13.4 million. Combined, the two make up less than a fifth of the total number of mobile subscribers in those five regions ComScore said.

ComScore is careful to point out that the share for iOS includes users on iPhones, iPods, and iPads, with … Read more
