Certifications have nothing to do with liking Microsoft or not. I know a guy that is the most FANBOY in the world for NetBSD, FreeBSD and some Linux Distros, tottaly hates Microsoft and Windows, and has the most complete curriculum of Microsoft. MCSA, +M and +S; MCSE, +M and +S. Why? Because if he only had LPI (Linux Professional Institue) and Linux + from CompTIA he would not have a job. About Windows being compatible with everything, well ... I think its the other way around. (Things are made thinking of Windows) PC parts, for example, have they drivers done for Windows. Most of PC parts manufacters dont make Linux Drivers. Linux could be as compatible as Windows if the big guys made drivers (drivers is just an example) for it. Bubye. P.S: I am not defending Linux. I am tottaly a Windows Fanboy. But Im not blind, as most of Linux Fanboys.
