Pros
Very bright people, especially in R&D. Disruptive technology that has a clear ROI and has become a de facto stardard for Fortune 1000 companies. The company is poised to be able to extend it's domination of server virtualization to the desktop and the cloud - a unique opportunity to shape the computing landscape for years to come. The company is more of an engineering driven, meritocracy than most other companies in the technology sector.
Kontras
Marketing has been weak and the company has been slow to react to Microsoft FUD. Although the company is an "independent" company of EMC that is traded on the NYSE, there is still the issue of EMC having a controlling interest (86% of the stock). The Chairman of the Board, Joe Tucci, fired the founding CEO, Diane Green, in July, and the stock has plummeted precipitously.
