Much easier? your must be kidding!
If it is really much easier, then why require 14 exams to become fully MCSE certified?
Whats more, Ubuntu and Kubuntu is now using more GUI, less command lines. Have you checked them, with version 9.04? of course 8.x and earlier is different when it comes to installing and delete software/applications.
Yes, I have Ubuntu and I actually like it a lot.
As for requiring 14 exams to become ceritfied, if you want to be certified, you have to PROVE your competency, through experience or education or both. MS sets standards on HOW well educated a person must be when it comes to dealing with Windows.
Remember, those certifications may not mean much if companies are NOT asking for them but a lot of companies do ask for them and pay more for MSCE engineers.
