Conclusion from the Article:
"The basic question here is, can solution providers count on Linux to fill the gaps? The simple answer is yes.
SUSE Linux Enterprise Desktop 10 has the feature set, compatibility and flexibility to meet the needs of most corporate desktop users. What's more, at a price point roughly one-tenth of what Vista and Office 2007 will cost, SUSE Linux becomes harder to ignore.
That said, there still will be challenges. Channel players will need to train employees and customers on Linux, equivalent applications may not exist in the Linux world to meet line-of-business needs, and inherent complexities can slow the adoption of Linux.
Microsoft delivers what corporate desktop users need as well, but also provides "the comfort of an old friend" factor, since most users are familiar with Windows".
