Mailbox for iPhone arrives to keep us on top of Gmail, aims for true inbox zero (video)

Orchestra thinks its new Mailbox app for the iPhone has a simple solution to the glut: treat email like task management. Along with reducing mail deletion to a single swipe, it lets readers postpone action until the evening, the following day or whenever it's easier to handle. It may come in handy for a few power users as well when it supports multiple accounts and can send push notifications. There are a number of caveats beyond just the iOS-only nature, however -- it supports just Gmail for now, and it doesn't have ways to assign custom labels or select multiple messages at once, like Google's app. When Mailbox is free, however, it's worth a try if your inbox has ever looked more like a monument to neglect than a clean slate.</div></div><iframe allowfullscreen="" frameborder="0" height="300" mozallowfullscreen="" src="http://player.vimeo.com/video/54553882?portrait=0" webkitallowfullscreen="" width="400"></iframe></div>

Nikkei: BlackBerry to stop selling phones in Japan, no longer able to justify

<div dir="rtl" style="text-align: right;" trbidi="on"><hr dir="ltr" style="text-align: left;" /> <div class="copy post-body" dir="ltr" style="text-align: left;"> <div class="image-container" style="text-align: center;"> <img alt="" src="http://www.blogcdn.com/www.engadget.com/media/2013/01/rim-2013-01-24-600-5.jpg" /></div>It looks like Japan won't be a part of BlackBerry's BB10 launch plans now or anytime in the foreseeable future. According to a report from <em>Nikkei</em>, BlackBerry has decided to stop selling phones in the country, at least in part because it wasn't able to justify the cost of making the necessary language modifications to its new operating system. As <em>Nikkei</em> also notes, however, BlackBerry has seen a particularly steep drop in market share in Japan, where it now stands at just 0.3 percent. We've reached out to BlackBerry about the news and are awaiting comment.<br /> <strong>Update:</strong> We've received a statement from BlackBerry confirming that it has no plans to launch to launch BB10 devices in Japan at this time, although it adds that it will continue to support its customers in the country. The complete statement is as follows:<br /><blockquote> We are in the process of launching BlackBerry 10 globally in key markets and we are seeing positive demand for the BlackBerry Z10 in countries where it has already launched. Japan is not a major market for BlackBerry and we have no plans to launch BlackBerry 10 devices there at this time. However, we will continue to support BlackBerry customers in Japan.</blockquote></div></div>

No, it's not that the pub is out of your favorite ale, nor is it that you're 0-for-6 with lame pickup lines. You've been texting, tweeting and checking in all night, and you're paying for it with that red sliver in the corner of the screen. So what do you do? Give up your primo spot at the bar and find an outlet somewhere in the corner? Not a chance -- it's time to pull out your coaster-sized Epiphany One Puck, set a cold brew upon it, and connect your phone for some juice. Who knows, the Puck might also help you break the ice.</div><div dir="ltr" style="text-align: left;">The idea to use heat disparities for power is over two centuries old, and we've seen larger concepts make use of thermo-electrics. The One Puck brings mobility into play, providing up to one amp of current to any device that charges through a USB cable, including Android devices and iPhones. Just place a hot object (a mug of cocoa) on the red side or a cold object (iced coffee) on the blue, then plug in your phone.</div><div dir="ltr" style="text-align: left;">The team at Epiphany Labs has loftier goals than simply charging cell phones, but all good ideas have to begin somewhere. The first prototype is ready and Epiphany is looking to Kickstarter to bring the project to fruition. An early pledge of $99 includes a One Puck expected to retail for $150, while a pledge of $135 adds some custom engraving, just in case you want to count out the possibility of a resale before you even take delivery. You can head past the break to watch the prototype in action, and check out the source link to peruse the project's funding page.</div></div><iframe allowfullscreen="" frameborder="0" height="360" src="http://www.youtube.com/embed/h_XzSnqo4Ps?feature=player_embedded" width="640"></iframe></div>

Lemons to lemonade: how manufacturing and mechanical setbacks shrank the Wikipad

Wikipad President of sales Fraser Townley says it was always in the cards -- but it was supposed to be the company's <em>second</em> tablet, not its first. Business, of course, doesn't always go according to plan. Just before the Wikipad's planned October launch, the company stayed production to refine the product's gamepad element, Townley told us, addressing a technical hiccup that could have troubled customers. Not too long after that, the company's screen supplier told them the part they had hoped to use for the Wikipad's 10.1-inch display was being discontinued. Salt? Meet wound.<br /> <span>Wikipad set out to make the best of a bad situation: it skipped a step. "The 7-inch was always in our roadmap and on our plan," Townley told us, "we just accelerated it." That decision was partly made to please the community, which was a little</span><span> </span>concerned about price<span>. At $249, the new Wikipad is certainly easier on the pocket book, but the redesign delayed the product <em>just</em> long enough to leave it teetering on the edge of a new generation -- the next </span>Tegra chip<span> is right around the corner. Fortunately, so is <em>another</em> Wikipad -- Townley told us the tablet's original 10.1-inch form would be out by the end of the year. He couldn't say if the delayed slate would be using NVIDIA's latest, but he left the possibility wide open. </span><span>"</span><span>There would be no point in launching a Tegra 3 tablet just months before the launch of Tegra 4, would there?" he joked. "We'll keep up with the market." An admirable goal, to say the least. </span><br /> </div></div>

Wikipad in miniature: 7-inch gaming tablet to debut in spring for $249, 10.1-inch sees further delay

<div dir="rtl" style="text-align: right;" trbidi="on"><div dir="ltr" style="text-align: center;"> <br /> <img alt="Wikipad in miniature 7inch gaming tablet to debut in spring for $249, 101inch sees further delay " data-src-height="340" data-src-width="620" src="http://www.blogcdn.com/www.engadget.com/media/2013/02/miniwikipad620.jpg" /></div><div dir="ltr" style="text-align: left;"> When a company delays a product for "minor refinement," we typically expect to see small changes that contribute to a stronger overall product. That wasn't Wikipad's approach -- when it took its namesake gaming tablet into the lab for "minor" tweaks, it took a few inches off its screen size. The Wikipad is now a 7-inch tablet, slated to launch in spring for $249. It's smaller, the company says, but no less powerful -- it's keeping the Tegra 3 GPU the original build promised, not to mention 1GB of DDR3 RAM, 16GB of Flash memory, a 2-megapixel front facing camera and a 1,280 x 800 resolution display.</div><div dir="ltr" style="text-align: left;"> Wikipad's President of sales, Fraser Townley, told us the gamepad design hasn't changed much either. "We took the pinball wizard approach," he said. "We made everybody in the room shut their eyes, and try the controllers. It's not about the look, it's about the feel. Once we got the feel right, <em>then</em> we could worry about the look. That's how the ten inch was born, and that's how the seven inch stayed the same." The attachment boasts new buttons (now labeled a, b, x and y) with a chrome finish, but seems otherwise unchanged. Wikipad is mum on specific availability, but we're told we can expect to hear more after Chinese New Year. As the 10.1-inch original design? It's still coming, but Townley couldn't it narrow it down further than "before Christmas." Read on for Wikipad's official press announcement, or click here to find out how the tablet was cut down to size.</div></div>

Nothing's changed from the WiFi-only version apart from the additional micro-SIM slot, of course, and although there's no confirmed pricing, it's expected to cost 29,800 yen (around $318, a little more than in the US) when it pops up online. Given the rate at which new Nexus devices disappear from the Play store, those eager for one from the first batch should think about clearing their diaries, and adding "click refresh" to their weekend to-do list, a thousand times over.<br /> </div></div>
