In "Why Apple Can't Sell Business Laptops" Forbes gives the case to be pro-Dell.  The author points out that Dell has 32% of the computer market within companies that have more than 500 employees.  He then explains this happens because Dell makes machines that are constantly the next generation beyond the previous laptop – a little better, a little faster, a little cheaper.  Comparing the new Lenovo Z to the Mac Air, the author concludes that anyone who sits in a corporate office, with a lot of corporate IT requirements, who wants the next small laptop would find it easiest to fit the Dell product into their work.

He's right.  Which is why investors, employees, suppliers and customers should worry.

Everything described is Lock-in.  Dell has focused on big IT departments, and sells products which cater to them.  Dell is listening to its dominant customers.  Each quarter Dell gets more dependent upon these customers – and walks further out on the PC gangplank when servicing their needs. 

But, large corporations are laying off more workers than any other part of the economy.  Both in absolute numbers and as a percentage of employment.  They are not the "growth engine" or the companies that will lead us out of this recession.  And while Dell caters to these customers, Dell is missing major shifts that are happening in how people use computers.  Shifts that are already demonstrating the market for traditional laptop technology is waning.

In PC technology, people are moving away from laptops and toward netbooks.  By far, netbooks have overtaken laptops as users shift how they access the web and get work done.  Additionally, people are moving away from traditional computing platforms for lots of things, like email and web browsing (to name 2 big ones), and using instead mobile devices like Blackberry and iPhone.  Apple appears to be very careful to not chase the netbook curve, instead appearing to advance the mobile device curve with future iPhones and a possible Tablet product. 

As Dell keeps getting closer and closer to its "core" customers, its customer and technology (traditional PC) Lock-ins are making it increasingly vulnerable.  When users simply stop carrying laptops, what will Dell sell them?  When corporations move applications to cloud computing, and users no longer need their "heavy" laptop, where will that leave Dell?  

The Forbes writer made the big mistake of measuring Dell by looking at its past – and glorifying its focus.  But this points out that Dell is really very vulnerable.  Technology is shifting, as are a lot of users.  The author, and Dell, should spend more time looking at the competition — including solutions that aren't laptops.  And they should spend more time building scenarios for 2015 to 2020 — which would surely show that having a better "corporate laptop" today is not a good predictor of future competitiveness for changing user needs.

Apple keeps looking better and smarter.  Instead of going "head-to-head" with the PC makers, Apple is helping users migrate to mobile computing via different sorts of devices with better connectivity (the mobile network) and lighter interfaces.  They are providing applications that support a wider variety of user needs, like GPS as a simple example, which make their devices addictive.  They are pulling people toward the future, rather than trying to hold on to historical computing structures.  As the shift continues, eventually we'll see corporate IT departments make this shift – just as they shifted to PCs from mainframes and minicomputers throwing IBM and DEC into the lurch.  As this shift progresses, the winners will be those with the solutions for where customers are headed.  And Dell doesn't have anything out there today.
