First came the PC, then the notebook and netbook. Now we fast forward to the smartphone and the tablet. These new devices are taking the technology world by storm. Apple (AAPL) could sell 30 to 65 million iPad 2s this year.

As a result, The PC industry is bleeding badly. Look at these numbers:

• February revenue from PC makers in Taiwan is down 20%. The number is significant because Taiwan manufacturers 90% of all PCs.
• Hon Hai (HNHAF), which makes Apple products and PCs for Dell (DELL), saw shipments down 18% in February, as reported in Financial Times.
• Gartner, a research consultancy, lowered PC shipments by 5% to 387.8 million units this month.

Intel Corporation (INTC) and scrappy Advanced Micro Devices, Inc. (AMD) are two tech companies that have been fighting in the microprocessor market for longer than many of us care to remember. Intel controls the majority of the PC processor market for consumer machines and business servers, but AMD always seems to be there to mop up market share with as much gusto as it can. Enter the latest battle originating from AMD's end: recruiting the red-hot Acer to power its servers with AMD chips.

Here are some highlights from this past week's earnings coverage on BloggingStocks:

• Abercrombie & Fitch Co. (ANF) received an analyst's upgrade ahead of next week's Q4 earnings report.
• Acer Inc. reported its highest quarterly earnings in almost three years due in part to growth in shipments.
• Baidu Inc. (BIDU) swung to a better-than-expected Q4 profit, with strong revenue growth, and offered rosy guidance.
• Biogen Idec Inc. (BIIB) offered an upside surprise as well as full-year earnings above Wall Street estimates.
• Coinstar Inc. (CSTR) strong quarterly results and guidance, as well as litigation concerns, failed to inspire Wall Street.
• Coca-Cola Co. (KO) posted strong Q4 and full-year earnings results due to growth in emerging markets.

Taiwan's Acer Inc. hasn't become the world's second-largest personal computer manufacturer for nothing. In its most recent quarter, the company announced that it attained its highest profit in almost three years, mostly at the expense of the company it recently displaced from the number two spot, Dell (DELL). It is still behind global computer leader Hewlett-Packard (HPQ).

At the same time it has grown shipments, it has kept an eye on profits, which is impressive. In general, rapid market share gains means margin cuts, but not here. Acer, which just four years ago seemed in disarray as it tried to find out why it was being beaten in the PC game, has apparently figured it out.

Taiwan's Acer has been on a tear recently. It markets the eMachines, Acer and Gateway computer brands and overtook Dell Inc. (DELL) recently to become the second-largest computer seller in the world. It may not be the most innovative, but it is selling a large amount of PCs every quarter. Its presence is large in the U.S. retail sector, where Dell's efforts over the last 18 months are still not where they need to be.

Now that Acer Chairman J.T. Wang wants to see Apple's (AAPL) new iPad tablet computer, one has to wonder why Acer cares at all. Although Amazon, Inc. (AMZN) already has the Kindle e-reader device (and ready to unveil a third-generation product to compete with Apple), Acer's Chairman may not realize that Apple is not wanting to compete as a tablet PC manufacturer.

Taiwan's Acer became the world's second-largest PC maker in 2009 by getting very aggressive in retail with pricing and positioning its three brands across all pricing segments. The eMachines brand is entry-level, the Acer brand seems to be mid-level and Acer has positioned the Gateway brand as a premium product.

All told, Acer's might unseated Dell (DELL) and the company shows no signs of slowing down sales. It even was an early participant in the netbook category last year, helping it capture sales in that red-hot category as well.

Global shipments of PCs in the fourth quarter. What is propelling the rise? As you might guess, it is price. Prices for PCs were lower in 2009 than the year before. The average selling price was estimated at $660 dollars, though it may have been lower. In 2008, the price was $771.

As for shipments by companies, Hewlett Packard (HPQ) was number one, followed by Acer, with Dell (DELL) in third place. Shipments of netbooks, which are smaller and have less processing power, accounted for a biggest share of the market.

For a company that hasn't even admitted to a new product, expectations are awfully high. The word is out that Apple (AAPL) will be unveiling a tablet computer at a major product launch this month.

Former Google (GOOG) exec Lee Kai-fu put out on his blog that he knows its coming, citing an anonymous source, and that the device would sell for less than $1,000. It's going to have a 10.1-inch screen and three-dimensional graphics, he continued, according to a Bloomberg News report, saying it would look like a large iPhone.

Acer Inc. of Taiwan has Hewlett-Packard (HPQ) of the U.S. in its sights to become the world's largest manufacturer of PCs. To do that will be no easy matter, as HP's rampage in sales in the past 24 months has put it way ahead of former number two Dell (DELL) and, for the first time, made it a $100 billion company (annual sales). But Acer has not tread lightly either, gobbling up the Gateway and Packard Bell brands.

Where can Acer work on its plans for global domination? China, of course. The company will increase sales training and work on upping its retail network in China by 30% as it chases the fastest-growing PC market in the world. So far, Acer's mindshare in China is in fifth place due to its inability to be recognized for the global PC behemoth it is. Acer intends to change that in China.

PC makers like Hewlett-Packard Corp. (NYSE: HPQ), Dell Inc. (NASDAQ: DELL) and Taiwan's Acer have seen computer sales decline in the past year as consumers faced a recession and tightened wallets.

Now, this isn't the first time PC sales have slumped, but it did send a red flag up a bit to those the sell the most: how about diversifying a little bit?
