THE MOTOROLA DROID

I have been playing with the Motorola Droid on the Verizon network for the last couple of months.  My first reaction to the Droid was that it did not stack up to my iPhone.  While nothing has changed that conclusion, I have developed some respect for the Droid as it has proven a very decent phone.  I have not had any trouble with it; it has performed well for me and it has the advantage of using the Verizon network, which provides better coverage than a number of its competitors. You can learn more about the Droid and its features on the Motorola website at www.motorola.com/Consumers/US-EN/Consumer-Product-and-Services/Mobile-Phones/ci.Motorola-DROID-US-EN.alt or on Verizon’s site at http://phones.verizonwireless.com/motorola/droid/#/home.

The Droid is a slider style phone and has a physical keyboard.  The physical keyboard is, perhaps, its weakest link.  The keyboard has small level keys.  They do not have raised ridges, such as RIM uses with some of the Blackberry models.  I prefer the raised ridges as they make it easier to use.  Raised ridges on a slider phone, however, could pose a problem as they would either require extra space making the phone cumbersome or interfere with the sliding process.  In truth, I prefer the virtual keyboard option and rarely use the physical keyboard.

The Droid has a 5mp camera, complete with a flash unit. It takes very decent pictures.  It also takes high quality movies.  As with most smart phones, you can play movies and music on it.  The Droid comes with 16GB of internal memory, but you can add more through the use of micro SD cards.  The phone came with a 16GB micro SD card installed and supports up to 32GB micro SD cards.

The Droid uses the current iteration of Google’s Android operating system.  I have worked with the Android system since shortly after it came out and I like it.  It works smoothly and easily, bringing substantial power to the smart phone without burning up the battery.  Like the iPhone’s OS, the Android system allows for the use of Apps or applications.  In fact a number of Apps available on the iPhone also have Android versions.  The variety of Apps for the Android system does not approach that available for the iPhone yet; but you can get a lot of usable Apps for the Android phones.

IS THERE A BLESSING FOR THE SAR?

In a scene from the musical “Fiddler on the Roof“, the Jews of Anatefka understanding that Judaism has a blessing for everything ask the Rabbi “Is there a proper blessing for the Czar?” He pauses and then chants: “May God bless and keep the Czar… far away from us!” Although the spelling and the meaning may differ, the principal is the same. ‘Keep the SAR far away from us’.

“SAR”, an acronym for Specific Absorption Rate, relates to the body’s absorption of radiation emanating from a mobile phone. Intermittently, we hear frenzied concerns that cell phones cause brain cancer. Studies to date have proven largely inconclusive. Accordingly, I have not found them convincing one way or the other. Remember, however, that the cell phone has only recently become a part of the daily routine of such a large portion of humanity. We will know a lot more in 30 years, but by then, many of us may already have suffered irreparable damage. Don’t forget that people did not consider cigarettes dangerous to health for a very long time. While I intend to monitor the results of future studies, prudence suggests implementing some precautions in how we use our cell phones. bronchitis cipro

In the US, the FCC imposes a SAR limit of 1.6 watts per kilogram (”W/kg“) over a volume of 1 gram of tissue. Europe uses a standard of 2W/kg averaged over 10 grams of tissue. Many phones have come out first in Europe and then later in the US.

For some time, people have purchased unlocked GSM phones in Europe and brought them back to the US. If you wish to reduce exposure to SAR, you may want to wait until new models come out here.

The theoretical danger comes from the fact that basically, the RF waves ”cook“ tissue by heating it. While use of the cell phone held up to your ear for short periods of time may pose a minor risk, logic dictates that, if the risk exists, the longer you hold the phone by your ear, the more likely that brain tissue near the ear will suffer heat damage. Does this mean that we should all dump our cell phones or that the Surgeon General should require a warning printed on the back of the phone? Probably not, but, common sense suggests that we should exercise some caution. RF waves dissipate over distance. The farther that we keep the phone from our body, the less likely that it will cause any problem for us. Using the phone’s speakerphone and keeping the phone on a desk or table when you talk offers one way of reducing exposure. As Bluetooth uses a lower power, it poses a smaller risk and, therefore, using a Bluetooth headset and keeping the phone in a brief case seems prudent. A wired headset does not generate radiation, but generally results in keeping the phone closer to our bodies.

Selecting a phone with a lower SAR also should reduce the risk of exposure. CNET has a nifty chart showing the 10 highest and l0 lowest SAR rated cell phones in the US and also providing information about other phones on a lookup basis. You can access the CNET chart at http://reviews.cnet.com/cell-phone-radiation-levels/?tag=lnav. I found it somewhat surprising that there appears little consistency within manufacturers and that some of the highest SAR phones had siblings in the lowest category. depakote numbness

Battle for Haditha movies According to CNET, the representatives in the highest category include several Motorola phones, one from Samsung and two versions of the Blackberry Curve.

The 10 lowest included phones from Motorola (two iterations of the Motorola Razr the Razr V3x and Razr2 V8), five phones from Samsung and two from Nokia. The Palm Centro models ranged from 0.74 to 1.35 W/kg, while the Treo models ranged from 1.26 to 1.5 W/kg. The original Apple iPhone came in at 0.974 W/kg and the iPhone 3G rates a 1.38 W/kg. Memory size appears to have no impact on the ratings. The Blackberry Pearl models lists at 1.22 to 1.48 W/kg.
