The Solar Surge from NovoTek uses the sun to charge an external supplemental battery enclosed in a case that surrounds the iPhone. The company claims this is the first solar charging solution approved by Apple,and it works with the iPhone 3G,3GS and iPod Touch. A two-hour session under the sun provides about 20 minutes of talk time. To help figure out how much charging is needed for other tasks,the company provides an iPhone app and website calculator. Input the type of weather,plus how much you plan to use the unit,and the app will tell you how much charging you need. The iPhone version is $80,while the iPod Touch model is on sale for $53. A Move on WiiLast week,Sony unwrapped PlayStation Move,Sonys answer to the Nintendo Wiis wand,at the Game Developers Conference 2010 in San Franciscio. The PS Move works with its eye video camera and software game titles designed specifically for remote,one-handed wireless control of 3-D action. While the device will control all varieties of kicks,swings and strokes,there also are controller buttons for more conventional shoot-em-ups. Later this year,the PS Move will be available in a starter pack,bundled with the Eye camera and a game title,for about $100. It will also come as a stand-alone product,and eventually arrive packaged with the PS3 console hardware. Another e-readerSamsungs new e-book is a curious combination of useful features and an important missing feature. For now,the $299 E60 lacks 3G cellular capabilities,a notable omission when compared to the Kindle and Nook,both of which are also priced lower. But,like the Nook,it will have Wi-Fi for downloading content. Samsung is boasting of the devices ability to enable users to annotate text,write notes and share this content with others. To do so,the E60 includes an electromagnetic resonance stylus pen. The E60 includes apps such as a journal,journal,scheduler and memo for writing. You also can synch your Outlook calendar with the e-reader,which is a pretty handy trick.
