The new iphone 3G might be phat and all, but surely the combination of a large touch screen display, 3G connectivity and relatively small size makes a potent combination for poor battery life. Sanwa forsees that problem and has a solution in the form of the 400-BT001. This rechargeable external battery will provide the iPhone 3G with extra 3.5 hours of talktime, 7 hours of video playback and more than 5 times that amount when it comes to non-stop audio. Each of the 1,200mAh Lithium Ion battery is equipped with a retractable USB cable and a LED that indicates the remaining battery life. The Sanwa 400-BT001 will add another 50 grams to your iPhone 3G, but the benefits far outweigh the sacrifice. At $46 a pop, this is relatively cheap.

Intel has been quite successful at marketing their “Centrino” brand. Many consumers simply think that they “need” Centrino to get Wi-FI, which is a powerful purchase argument. As notebooks continue to take share worldwide, Intel is officially releasing its Centrino 2 and Centrino 2 vPro offerings today (laptops have already been announced by partners), so what is it and what’s new?

Often falsely described as a “processor” or “processors”, Centrino 2 basically is a “package” or “combo” of Intel chips with the following elements:

• Intel CPU
• Intel Chipset (it controls the main board) with Integrated Graphics (cheap but slow)
• WiFi-N (the fastest) adapter and an *optional* WiMAX wireless networking adapter
• (wired) Gigabit Ethernet (vPro only)

In this post, we’ll go over what the specifications mean to you as a consumer (performance, form factor, connectivity and battery life) and what you can expect. We’ll also follow the first real-world tests as they come up.
