Popular iPad cutting into computer sales

Hewlett-Packard Co.'s consumer PC sales plunged 23 percent last quarter, and the company lopped $1 billion off its annual sales forecast. And while rival Dell Inc. beat analysts' estimates because of corporate demand, its sales to consumers slumped 7.5 percent. More than 70 million tablets like the Apple Inc. iPad will be sold in 2011, a total that will balloon to 246 million in three years, according to Jefferies & Co.


"You're walking into a buzz saw," Jane Snorek, a senior research analyst at Nuveen Asset Management in Milwaukee, said of the iPad. Her firm manages more than $200 billion in assets. "The tablet is going to replace at least the home computer."


At 7.3 inches across, with a color screen and an array of popular downloadable games like Angry Birds, applications for watching movies and reading magazines, and software for word processing and spreadsheets, the iPad has siphoned off more PC sales than analysts and executives predicted.


Apple, based in Cupertino and run by Steve Jobs, sold 4.69 million iPads last quarter, for a total of about 20 million since the device was released in April 2010.


The PC market, by contrast, declined last quarter. Global shipments fell 3.2 percent, hurt in part because some people bought tablets instead, research firm IDC reported last month.


While rivals including Research In Motion Ltd., Motorola Mobility Holdings Inc. and Samsung Electronics Co. have begun selling tablets, those have yet to gain wide acceptance.


The lack of viable competitors was felt across the PC industry in the first quarter. Microsoft Windows sales fell 4.4 percent to $4.45 billion. Its net income of $5.23 billion was eclipsed by the $5.99 billion reported by Apple, which topped its rival in that measure for the first time in 20 years.


At Intel, whose processors run more than 80 percent of the world's personal computers, growth in the PC-chip division came mainly from emerging markets and corporate sales.


Hewlett-Packard, the top PC maker, on Tuesday cut 20 cents per share from its annual earnings forecast, to $5, excluding items. The revised outlook sent the shares tumbling 7.3 percent on the New York Stock Exchange on Tuesday and left the stock down 12 percent since the last business day before L?o Apotheker took over as chief executive officer on Nov. 1.


"L?o comes in just as the tablet is taking off, and the consumer PC market is waning," Snorek said.


In a conference call Wednesday, Apotheker bemoaned a "bifurcated" PC market, where companies are spending and consumers aren't. Sales in the company's personal systems group fell 5.4 percent to $9.42 billion last quarter.


At Hewlett-Packard, full-year sales will be $129 billion to $130 billion. In February, HP had predicted full-year sales of $130 billion to $131.5 billion and earnings of at least $5.20 per share. Third-quarter forecasts from HP also missed analysts' estimates.


Dell was able to top estimates with its quarterly results Tuesday because of demand from businesses. Its sales to consumers fell partly because of competition with the iPad and other tablets, said Brian Gladden, chief financial officer of the Texas company.


"It's clearly a topic of discussion and it's a factor that's impacting the weak consumer demand," he said in an interview.

Plasma Cutting Tables - A Revolution in Machinery Manufacture


Scientists have proved that apart from the three states of matter which are known to them, namely solid, liquid and gas, there is a fourth type known as plasma. They do not exist naturally on earth. When a gas is heated to very high temperatures, tremendous amounts of energy are transferred to the atoms which ionize into its basic components, nuclei and electrons. Plasma is known to be an excellent electric conductor. Plasma cutting tables have the cutting blade digitally connected to the computer. Therefore computer will control the blade and monitor the cutting works accordingly to the specifications fed into it.

The expected design should be fed into the computer memory in advance making it possible to produce perfect cut related to the specific design. Making use of such equipment has become an integral part of many industries where the accuracy of the cut is considered to be a crucial aspect. The use of this novel technology ensures that the manufacture of tool components, various signs and novice industrial products are easily and accurately accomplished. You can customize the cutting patterns software to suit your business requirements. The greatest advantage is that it is possible to construct this device at your own workshop. One should possess good knowledge of various electric circuits, software languages and digital controllers to do it. Homemade equipment should be supported by adequate software. It is also advisable to conduct some research on how to build this equipment at home before actually trying it. Various materials are required to build this device at your workshop. They include nuts, threaded rods and linear bearings. One might also need a stepper motor with adequate power. The power of the motor will depend on the intensity of the job. A computer with Linux or other suitable operating system is mandatory.

The software that will actually monitor the cutting procedures should be pre-loaded onto the computer. A printer should be connected to the computer through the parallel printer port. A breakout PCB provides additional security to your electronic circuit. The greatest application of plasma cutting tables is in the machinery manufacturing industries. Since they are capable of delivering high precision cuts, they are widely used. Human error that can occur in manual operation is nullified with the use of this equipment. There are many different models of plasma cutting tables available. Some famous brands are Miller, Simadre, Lincoln and Esbab. The Simadre brand is quite reliable and is an economic choice. The type of equipment to be used will depend on the uniqueness of the metal which needs to be cut. Also, all necessary safety measures should be strictly adhered to while working with this equipment.
