"Right now, Linux won't displace Windows in any significant
percentage, at least in markets where Windows already rules the
roost. That's part of what makes the netbook market such a fierce
battleground: in Microsoft's eyes (and in the eyes of many Linux
users), Linux has a good chance of proving itself there as a
prelude to making strides elsewhere.
"But it will take more than just making Linux available to
people as a hardware preload option to put it on even footing with
Windows in the notebook world. The rest of the software in the
Linux sphere has to also compete -- either that, or Web-based
equivalents of applications routinely used in Windows will have to
become preferable alternatives."
