The Logitech ZeroTouch is a mount for Android smartphones that promises to enhance voice control while driving. However, it's too buggy to be truly useful.

The LG G5, Samsung Galaxy 7 and HP Elite x3 premiered at the Mobile World Congress on Sunday, and they offer three very different views of the world.

Even by the new standards of cell phone advertising, the run-up to the HTC ThunderBolt -- Verizon's first 4G LTE smartphone -- was elaborate and expensive. Gatefold ads in mass-market magazines and high-profile TV spots on the Oscars, NASCAR and college basketball all proclaimed that there was a new 4G phone coming from Verizon, but not much else. Inquiries made of HTC and Verizon were met with official shrugs. The company spent many millions of dollars advertising a phone and didn't tell anyone when it would be on the shelves.

Because of the way the U.S. mobile phone market is structured, it's next to impossible to find an unlocked phone that isn't loaded with bloatware. For those who want a carrier-independent smartphone, an enticing option is the Nexus S, a very nice successor to Google's Nexus One, which did so much to popularize the Android operating system.

Good writers borrow, great writers steal, or so the saying goes. Microsoft's new Windows Phone 7 (WP7) operating system borrows heavily from Apple's iOS and Google's Android but then takes the interface and navigation in an intriguing new direction, offering a user experience that at least equals and in some ways surpasses them.

Starting Wednesday, September 1, if all goes according to plan, you will be able to order one of the first in what will surely be an avalanche of Android -based tablet computers. That's the day the eLocity A7 , running Android 2.2 and based on the Nvidia Tegra 2 chip, will be available for pre-orders at Amazon.com.
