Qualcomm is updating 4G technology to its Gobi laptop modems and expanding its chip offerings that support 3G technologies.
The San Diego-based company announced at CTIA in Las Vegas that it will add, for the first time, LTE, or Long Term Evolution 4G technology to the roster of 3G technologies that the Gobi modem supports. 4G technology is expected to offer much greater data throughput than current 3G technologies.
Chipsets now available that support the Gobi API include:
MDM6600: HSPA+ data rates of up to 14.4 Mbps and CDMA2000 1xEV-DO Rev. A/Rev. B.
MDM8220: dual-carrier HSPA+ for data rates of up to 42 Mbps.
MDM9200: LTE data rates of up to 100 Mbps, backward compatibility to dual-carrier HSPA+
MDM9600: LTE data rates of up to 100 Mbps, backward compatibility to dual-carrier HSPA+ and EV-DO Rev. A/Rev. B
The company has released its proGreen series, which consists of six computers that are Energy Star 5.0-compliant, including two notebooks. 
The green notebooks, the LifeBook E780 and the LifeBook S710, come equiped with Intel’s Core i5 and Core i7 vPro power optimized processors. Fujitsu claims the laptops are 25 percent more energy efficient than their previous LifeBook models.
Fujitsu says the notebooks will also come with an 87 percent energy efficient AC adapter. The computers can run for up to 18 hours on their two batteries. The models have a green casing, reflect its environmental concerns.
“We are the first IT vendor to offer a complete range of environmentally-sound products,” says Rajat Kakar, vice president of the clients group at Fujitsu. “This product line offers all the environmental benefits along with maximum performance, but without a high price tag. Furthermore, businesses can achieve additional cost-savings with the resulting energy-savings.”
Apple just announced the terms of the deal for the iPad. Provided your iPad hasn’t gone through some catastrophic amount of damage “as result of an 
accident, liquid contact, disassembly, unauthorized service or unauthorized modifications,” suggests Apple then you’ll be eligible to take advantage of the company’s battery replacement service.
It will cost you $99 (plus $6.95 for shipping and whatever your local tax happens to be). When you send your iPad off to Apple, you aren’t just getting your same old iPad back in the mail after one week or thereabouts. Opting for the company’s battery replacement service will basically put you on the list for a refurbished iPad although the exterior case of the device will be brand-new, the underlying product will be one that’s gone through Apple’s fix-it procedures in some capacity.
When Apple receives a device for battery replacement, it essentially sticks the product in a “to be fixed” bin. In order to guarantee a rapid turnaround time for the iPad you’ve sent in, it’s easier to grab an identical item that’s been previously fixed off the shelf and send it your way. Once your device is fixed, it’ll go in the waiting line for someone else suffering from a near-dead battery. You’re not paying Apple for a refurbished unit per se; you’re paying for the entire process.
