PDA, RIP
The next big thing that wasn't�or was it?

IS IT time to declare the demise of the handheld computer, also known as the personal digital assistant (PDA)? A lot of people suddenly think so, for despite high hopes that the devices�made by such firms as Palm, Sony, HP and Dell�would someday become ubiquitous, annual sales have stayed flat at around 11m units worldwide. This compares poorly with PCs, around 130m of which are sold every year, and mobile phones, with sales of around 460m units. �The PDA market will never be a mass market,� says Cindy Wolf, an analyst at In-Stat/MDR, a market-research firm. Almost everyone who wants a PDA, she says, now has one.

Palm springs eternal
In contrast, sales of smartphones, high-powered mobile handsets capable of doing most things PDAs can do, are rising fast. Smartphones can be used to store addresses and phone numbers, download small pieces of software (such as games), browse the internet while on the move, store and play music, and jot down brief messages. And, of course, they are also telephones. Why carry both a phone and a PDA around, when you can carry a single hybrid device? Fewer than 4m smartphones were sold during 2002, but nearly 12m will be sold this year, says Neil Strother of In-Stat/MDR. Although final sales figures are not yet available, it seems very likely that sales of smartphones overtook sales of PDAs in the third quarter of this year.

�The PDA is dead,� says David Levin, the boss of Symbian, the leading maker of smartphone software. Anssi Vanjoki of Nokia, the world's biggest mobile-phone maker, agrees. PDAs without wireless connectivity are doomed, he says. Even as Nokia, Sony Ericsson and other handset makers build PDA-like functions into their smartphones, some PDA makers are adding phone capability to their handhelds.The two camps have arrived at the same result�a hybrid PDA-phone�from opposite directions.

David Nagel of PalmSource, the firm that licenses the Palm operating system to makers of phones and PDAs, dismisses the idea that one camp or the other has won. To say that there is a single �killer device� is, he says, an oversimplification, for there is room for a whole range of PDA-like devices in the marketplace�of which smartphones, in his view, are just one kind. PalmSource is, he says, well placed to compete with Symbian and Microsoft to provide the software to power pocket-sized devices.

Insulin Resistance- cause of ADD, diabetes, narcolepsy, etc etc

Insulin Resistance Insulin Resistance Have you been diagnosed with clinical depression? Heart disease? Type II, or adult, diabetes? Narcolepsy? Are you, or do you think you might be, an alcoholic? Do you gain weight around your middle in spite of faithfully dieting? Are you unable to lose weight? Does your child have ADHD? If you have any one of these symptoms, I wrote this article for you. Believe it or not, the same thing can cause all of the above symptoms. I am not a medical professional. I am not a nutritionist. The conclusions I have drawn from my own experience and observations are not rocket science. A diagnosis of clinical depression is as ordinary as the common cold today. Prescriptions for Prozac, Zoloft, Wellbutrin, etc., are written every day. Genuine clinical depression is a very serious condition caused by serotonin levels in the brain. I am not certain, however, that every diagnosis of depression is the real thing. My guess is that about 10 percent of the people taking

Could Narcolepsy be caused by gluten? :: Kitchen Table Hypothesis

Kitchen Table Hypothesis from www.zombieinstitute.net - Heidi's new site It's commonly known that a severe allergy to peanuts can cause death within minutes. What if there were an allergy that were delayed for hours and caused people to fall asleep instead? That is what I believe is happening in people with Narcolepsy. Celiac disease is an allergy to gliadin, a specific gluten protein found in grains such as wheat, barley and rye. In celiac disease the IgA antigliadin antibody is produced after ingestion of gluten. It attacks the gluten, but also mistakenly binds to and creates an immune reaction in the cells of the small intestine causing severe damage. There is another form of gluten intolerance, Dermatitis Herpetiformis, in which the IgA antigliadin bind to proteins in the skin, causing blisters, itching and pain. This can occur without any signs of intestinal damage. Non-celiac gluten sensitivity is a similar autoimmune reaction to gliadin, however it usually involves the

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed Scientists at John Carroll University, working in its Lighting Innovations Institute, have developed an affordable accessory that appears to reduce the symptoms of ADHD. Their discovery also has also been shown to improve sleep patterns among people who have difficulty falling asleep. The John Carroll researchers have created glasses designed to block blue light, therefore altering a person's circadian rhythm, which leads to improvement in ADHD symptoms and sleep disorders. […] How the Glasses Work The individual puts on the glasses a couple of hours ahead of bedtime, advancing the circadian rhythm. The special glasses block the blue rays that cause a delay in the start of the flow of melatonin, the sleep hormone. Normally, melatonin flow doesn't begin until after the individual goes into darkness. Studies indicate that promoting the earlier release of melatonin results in a marked decline of ADHD symptoms.
