Laptop computers, especially small and light ones, were supposed to be the way the computer companies kept mobile users as customers. It has worked pretty well. At most large PC companies like Apple (NASDAQ: AAPL) and Dell (NASDAQ: DELL), laptops outsell desktops.

The profits from the laptop business could be under siege. Little netbooks from manufacturer in Asia, lead by Acer, are making $500 ultra-small machines that are good for e-mail and internet browsing. Beyond that, they don't do much, but many consumers don't need anything beyond those functions. The products may be a good way for Acer to get market share from larger U.S. PC companies.

In a recession, these "netbooks," are fairly attractive compared to $1,200 laptops that have a lot of features many people don't want to pay for.

According to Reuters, "Up to a third of netbook sales reflect customers ditching their old desktops and laptops, analysts say."

Dell's share price is down to $12.50 from a 52-week high of $30.77. The company and its peers do not need more competition in a world where the economy is hurting and price competition is fierce.

It does not want new competition, but it got it anyway.

Investors tend to forget that some of the world largest PC companies are based in China, lead by Lenovo and Acer. The two companies run behind Dell (NASDAQ:DELL) and Hewlett-Packard (NYSE:HPQ) in global market share. But, that may be changing in a way that the two US companies will find unpleasant.

Research firm Gartner looked at PC sales around the world during the third quarter. According to Reuters, "Overall, worldwide PC shipments rose 15 percent from last year to 80.6 million units." To no one's surprise, growth in the US was slower, up 4.6%.

HP's global market share was 18.4% and Dell's was 13.6%. Acer rose to 12.5% making it the most improved of the three compared with last year.

Acer's secret is that it is selling netbooks, small PCs which usually cost under $500. Analysts have questioned whether consumers would want these because smartphones have many of the same functions. Acer has taken the gamble of ramping up production, a potentially risky move if the customers were not out there. The decision is giving them a chance to steal a march on the larger rivals.

The Acer move may say as much about what is wrong with US PC companies as its says about what is right at Acer. There are many people, especially in emerging markets, who are not likely to be able to spend $1,000 on a computer. And, the mobility of the US PC user is improving with the success of WiFi and 3G.

Dell and HP should be concerned every time they see someone walking down the street with a netbook. It has probably been sold to them by a competitor.

Everyone who's interested in the Dell to Wal-Mart retail scenario wants to get a better idea of just exactly what Dell intends to do over there. We all know that Wal-Mart (NYSE: WMT) is the "Low Price Leader", so how does this play out for Dell (NASDAQ: DELL)? Being that my Dell corporate headquarters spy drones are down for repairs and my Wal-Mart corporate spy cams have been taken off line, I can only speculate on the intended direction which Dell's move is going to take. Over at Engadget the response to this move has been tepid, or leaning towards not well received.

First, let me say that at its root this Dell move is an excellent idea. By that I mean Dell has needed a direct outlet to the consumer for quite some time. Some of the tech sector analysts where aghast when they heard of this move because they had quickly assumed that Dell was changing over their entire marketing strategy to volume by low price but I assure you that's not what's happening here. Dell will still be building the lion's share of its desktop computers to customer order and shipping them direct. Wal-Mart, for the time being at least, shall only be handling a couple exclusive Dimension desktop models and I expect a select few notebook and laptop models. I predict also that as Dell earns Wal-Mart shelf space, there will be other Dell branded consumer electronics moving in there, but probably never their full desktop line.

Wal-Mart is historically demanding in their requirements for wholesale purchasing. They set the prices, the volume and the time tables. It's very much a take it or leave it world when selling to Wal-Mart. To me, it's kind of a sign of desperation that Dell has opted to go this route. I honestly thought that a Radio Shack (NYSE: RSH) scenario would play out to a much greater advantage for Dell than this Wal-Mart strategy. Is this a sign that as consumers we're expected to cheapen our expectations when thinking of Dell? I assure you that is what will happen. I'm expecting to spend about $2000 on a new PC next year. Perhaps it will be a Hewlett-Packard (NYSE: HPQ) after all.

Now, if you'll excuse me, I have to get to work on these spy drones.

A fellow I know is preparing himself for a college education in veterinary science. Knowing that I slink around the internet tech world, he came to me looking for advice about what notebook computer he should buy. He plans to spend between $400 and $600 and he wants to get the most for his money (smart kid). He needs his machine for internet access, music downloads, heavy-duty emailing and of course for some school work.

It occurred to me that because my computer experience is limited to desktop models I might not be Andy's best source of information on the latest notebooks. So I told him that I'd present the question to our readers and deliver your input back to him. Knowing that our readers are some of the brightest minds on the internet, I have no doubt that Andy will get his best information right here on BloggingStocks.

So, the question is:

What is the best laptop computer that Andy can get for between $400 and $600 and what should he expect as far as speed, memory, peripherals and overall performance?

Last night's earnings warning from Dell bodes ill for Microsoft and Intel.

Having finished teaching Competitive Strategy and Environment last night to 36 MBA candidates, I am in a state of heightened awareness about the profound strategic implications of the Dell announcement. Here are four important concepts and the implications for Microsoft and Intel:

• Complementary goods. When people buy a new house, they also buy furniture and appliances. The furniture and appliances are complementary goods. When they buy a PC, they've got to purchase software. And when they buy Dell, they inevitably buy Microsoft software. As Dell's growth falters, Microsoft sales will be hurt as well unless Dell's competitors can take up the slack.
• Industry structure. There are very few industries where suppliers are able to negotiate the lion's share of the profits. The PC industry is one of the exceptions. Here, Microsoft and Intel have used what was a virtual monopoly to extract high profits from PC-makers. But this supplier power may be eroding -- due to the rise of AMD as a real competitive threat -- as Intel's latest earnings disappointment reveals.
• Generic strategy. During the 1990s when its market share climb was at its most aggressive, Dell was the low cost producer. As my Computerworld analysis reveals, in 1996 Dell enjoyed a 13.6% cost advantage over its biggest competitor at the time, Compaq. Dell passed much of this cost advantage on to its customers in the form of lower prices -- thus gaining market share. The loss of Dell's advantage suggests that Microsoft and Intel may want to find other horses to ride.
• Sustainable competitive advantage. Fast forward 10 years and suddenly Dell's cost advantage has been eroded by competition from Taiwan-based contract manufacturers to whom Dell -- and competitors such as HP -- outsource the manufacture of notebook computers. By depending on Taiwanese manufacturers, Dell eroded its competitive advantage since no barriers prevented these competitors from doing the same. Should Microsoft and Intel be dealing directly with the contract manufacturers?
