TV's as home computers

.
With the next generation of TV's being internet capable the home
computer is slowly becoming redundant. The latest TV's can
browse the web, check e-mail, view photos, stream movies and
play music. Documents can be created by online office programs.
The remote can be used in the same way as texting on a phone to
place words on the screen. Alternatively a wireless keyboard
can be used. Printing is attained by using a network or e-printer.
Files can be saved to a SD card or thumb drive. This is all achieved
by adding less than $100 to the price of the tv. Android is the most
popular operating system that allows this to happen, as it is small,
secure and requires no maintainance.

Open Office Draw

Click to Enlarge

Open Office suite has a particularly powerful and easy to use drawing component built in. Once the drawing is complete it can be integrated into the word processing or presentation section of the suite. Open Office is free so does not have to change formats and layouts to sell the next version, but keeps on improving on the last update. As it's free and backward compatible there is no reason not to use the latest version 3.3.
As the suite has a common base and all the other sections are added on, it means it will run quite happily on a pentium 3 with 256mB RAM.

Process Controller for home use

.

Further to Clive's discussion on Process control there is a small $40 device that is an educational tool but is quite capable of serious work, on the market. It is the "Arduino Diecimila' and is shown in the picture. A USB port on the left is connected to a computer for programming. By the thumb is a terminal strip that is used for the inputs (switches, sensors etc) outputs (leds, relays, actuators etc) communication (RS232, PWM etc). Once the device has been programmed using a simple instruction set it can then be put in 'Run Mode' and  disconnected from the computer.  The program should keep running for  up to 40 years. As the output signals are tiny a simple amplifier circuit may be required for useful applications. If all inputs and outputs are rated at less than 48 volts there are no safety issues.

Sales of Tablets are gaining on PC's

.

iPad-2

As Apple's iPad-2 has just gone onto the market they are clearly trying to stay ahead of the competition. It is faster, lighter and has camera's, which is partly to hold off the Android invasion. Apple's iPhone held the lead for two years but Google's Android has recently overtaken it. Apple are trying to keep ahead of the game with their Tablets.

The competition includes Google's Android, HP's WebOs, RIM's Playbook and Fujitsu's Meego. Microsoft has Tablets based on Win 7 but heavy hardware requirements and prone to viruses put it out of the race. Maybe Win 8 which will run on different hardware will help but could be too late. Competition has meant technological  advances are swift and large pondering companies can fall quickly, like Nokia.

As newer Tablets can use external monitors (TV's) and wireless keyboards (remotes) the PC's future for households is looking bleak. Games are played on Game Consoles. Office suites and Picture Editors are run from the 'Cloud'. Files can be saved on Flash drives or External USB drives. There is no need for a large unreliable desktop computer anymore.

Nokia and Windows Phone 7

.

Windows Phone 7

Android Phone

Nokia announced that Windows Phone 7 will be their main product. This is a last ditch effort to stop Android and iPhones from being the only relevant platforms. This announcement stripped Nokia's value by 18% in two days. How this is going to work with Nokia's Engineers that no nothing about Windows phone's software trying to fit it on a device that was  designed for the Symbian Operating System, is anybody's guess. After the Symbian System has been declared obsolete and development is to be stopped most buyers will look at the two main alternatives as Windows phone 7 will be at least a year away. By then iPhone and Android will be fourth generation devices. HP's WebOs will be a better contender for third place as it is ready now for production as a Phone, Tablet and Consumer PC.

Phones, Tablets and Touchscreen PC's.

.
As Mobile devices are now selling faster than traditional PC's the major manufactures have announced which Operating Systems they will support for the home users.

Apple and Android devices are presently taking up most of the new market, but there are a number of new contenders coming on line in the next few months.

Blackberry are producing the 'Playbook' which will also run Android Applications.
Nokia is going to use Windows Phone 7 as they are rapidly losing ground with Symbian.
HP, the biggest computer manufacturer, is swapping Windows for their own WebOs.
Fujitsu will use Meego for Tablets that Nokia  developed.
Google are releasing ChromeOs for Netbooks.
Most Korean and Chinese manufactures are building on Android 2 (phones) or Android 3 (tablets).
Apple will produce iPad2 to stay in front.

Consumers will be spoiled for choice over the next six months for mobile devices that will use software on remote servers ( ie on the cloud ) to search the Internet, do E-mail, Skype, Edit Documents and retouch photo's. This will also apply to Internet ready TV's.

Save your documents from a PC that won't boot.

.

When a PC refuses to boot the usual procedure is to reinstall the Operating System. This will mean that all files will be lost that were on the 'C' drive. This could be where your family photo's had been stored. Fortunately these can usually be saved with the help of a 'Live CD'. I use Puppy 5.20 for this job. Simply boot from the CD and then click on the 'SDA1' icon in the bottom left hand corner. This should display the 'C' drive in a file manager. Place a 'Thumb drive' in the USB port and it will appear as an icon in the bottom left corner. Click on it and it will open another file manager. Find the files to transfer from the first file manager and pull them across to the second file manager. This process will copy the 'C' drive files to the 'Thumb drive'. This live CD also has a program for removing 'Viruses' from the Windows partition and can often restore a Windows Operating System thereby saving a repair bill.
