Sony continues to lose money in it's entertainment division on sales of the PlayStation 3.And Nintendo continues to turn a profit on sales of the Wii.Then why are investors driving Nintendo's stock down and Sony's stock up?It's because they don't like thedirectionthat they're seeing Nintendo heading.Year-over-year profits at Nintendo are down almost 50% for the first half of 2009.

Remember when the typical cellular phone advertisement showed a woman with a small child near a broken down car on a dark highway? Cell phone in hand, she would call a tow truck and be on her way. The message--don't let this be you or your wife/mother stuck out here on the road without a cell phone for emergencies.

Back in that time, expansion was easy for the cellular providers. All they had to do was set up a few kiosks in the mall or a local retailer and wait for people to approach and sign up for new service. Contracts were typically one year long, and growth was simply made by adding new subscribers.

Netflix's Instant Watchingfeature allows subscribers of the DVD rental-by-mail service to stream a select group of 17,000 movies to a PC or a compatible device.

Atlanta is one of a handful of cities with 4G wireless service already available. This first salvo in the race to 4G is an implementation of WiMAX, which claims speeds comparable to Wi-Fi over much larger areas. I have been using 4G service for about two months now, and on the whole I'm impressed with it, but there are certainly some gotchas in comparison to using 3G cellular data service.

The WiMAX network was developed by Sprint and Clearwire with funding from industry heavy-hitters like Intel, Comcast, and Google. As such, there are several different vendors for WiMAX service, but they're all using the same network. I'm using Clearwire's CLEAR service, but as far as I know, there shouldn't be any performance difference between it and Sprint's 3G/4G service or Comcast's High-Speed 2Go.
