YOUR TECH: Dueling printers: HP-Kodak

The folks at Kodak have been rather intense this year in advertising their ink-jet printers as being less expensive to operate than those of rival manufacturers. I haven't heard any caterwauling from rivals Epson or Brother, but the people at Hewlett-Packard's ink-jet division, which, after all, invented the category, were none too pleased.

KELLNER: BibleGateway.com grows digital future

It's 16 years old, and it has the Bible in 100 translations. What else would a Web site called www.BibleGateway.com have to do? Published July 20, 2009

YOUR TECH: D5000’s versatility is impressive

What's the greatest feature of the new Nikon D5000? For starters, it can handle just about any task you throw at it, from landscapes to portraits to close-ups. Its built-in metering and autofocus features complement a 12.3-megapixel capacity, fast shutter speed and excellent image stability. Published July 15, 2009

KELLNER: Google to launch Chrome OS in ‘09

Google's announcement Wednesday that it would launch a computer operating system for developers to work with this year, and for the rest of us "in the second half of 2010," sent shock waves through much of the computer world. Published July 13, 2009

YOUR TECH: Satellite car TV offers 22 channels

It was fitting perhaps that Winston Guillory, president of Dallas-based RaySat Broadcasting Corp., dropped by just before the recent holiday weekend to demonstrate the AT&T CruiseCast service. Published July 8, 2009

Outwit your inbox

The daily flood of e-mail messages — like the McDonald's sign, "billions and billions served" — is unrelenting and frustrating to many. Published July 6, 2009

KELLNER: Speed, space and browsers

The recent arrival of updated versions of two popular Web browsers, Mozilla.org's Firefox 3.5 and Apple Inc.'s Safari 4.0, is perhaps more noteworthy than might first be imagined. Published July 6, 2009

YOUR TECH: 3GS just the best of its ilk out there

It would be painfully easy to say the iPhone 3GS, released last month, is just a better smartphone than any of its rivals, rattle off the assorted features and leave it at that. Published July 1, 2009

Egypt sends emissary on high-tech mission

Tarek Kamel, Egypt's minister of communications and information technology, was in Washington and New York last week to boost the nation's profile as an information technology, or IT, hub. Published June 29, 2009

KELLNER: Nikon’s Coolpix snaps in a pinch

As with every Nikon product I've used, I can find little fault with the Coolpix P90. The kind of photo-grabbing power in this unit is rarely seen at this price point, and the firm's commitment to ease of use is evident in just about every feature. Published June 29, 2009

YOUR TECH: Newest Kindle worth its price

Amazon.com's new Kindle DX is a great buy in e-book readers, even if the $489 price is 36 percent greater than the $359 price of its predecessor, which was released in late February. Published June 24, 2009

KELLNER: Opera browser OK, but iPhone sings

Last week's release of a new Web browser from Opera Software is very good, but I don't hear any angelic choirs. By contrast, the new operating system for Apple's iPhone, OS 3.0, certainly hits all the right notes. Published June 22, 2009

YOUR TECH: MacBook Pro worth price

Apple Inc. is a company that not only knows the basic recipe for a good product, but continuously works to refine and perfect that recipe without making a mess of things. Published June 17, 2009

KELLNER: A tale of two smartphones

Even before the confetti from the June 6 launch of Palm's Pre smartphone had been swept away, Apple Inc. came along to pop the last remaining Pre balloon. Published June 15, 2009

YOUR TECH: Sprint’s Palm Pre still in early stages

Perhaps, I'm thinking, this is a pre-release Palm Pre I have in my hands. That has to be it. Why else would Palm and Sprint ask us to fork over $300 for the new phone, with a promise to refund $100 when you mail in a form, and commit to a two-year service contract worth about $2,400? Surely this thing isn't the final, shipping, product, right? Published June 10, 2009

KELLNER: MiFi is intriguing, frustrating

A little more than five months ago, at the tail end of December, the folks from Novatel Wireless came by and demonstrated the MiFi 2200, a "personal" wireless hot spot, one that promises to put the speed of the Internet in a transceiver the size of a credit card, albeit with the thickness of several such cards.

YOUR TECH: Building a system in steps

If the word "staycation" has entered the lexicon thanks to the challenges of today's economy, I guess there had better be something to make staying home worthwhile. Published June 3, 2009

KELLNER: Microsoft’s Bing offers new search

The buzz was about Bing on Thursday as Microsoft Corp.'s Steve Ballmer took center stage at the D: All Things Digital conference near San Diego to announce the next step for the Live Search technology. Come Wednesday, Bing should be available to one and all at www.bing.com. Published June 1, 2009

BlackBerrys in bed? Danger lurks

If you bring your laptop computer or cell phone to bed, your partner may resent more than just the fact that you are working late. You might bring along a computer virus or invite an identity thief to jump in. Published May 27, 2009

YOUR TECH: Cool-er not as hot as Kindle

You remember that kid in high school who tried really, really hard, but never quite got it? I think I've found his digital cousin. Published May 27, 2009
