I’m doing this because, for almost two years now, I’ve been extolling virtues of moving to a fully virtualized desktop, all along promising to practice what I preach. So, now that I’m practicing it, I find myself questioning whether I should be preaching it. Let me clear before I start on the series. I have no regrets about virtualizing my desktop. I’m glad I did it and would do it again. I know that what I’m doing isn’t exactly what the various virtualization solution providers had in mind (in other words, targeting normal PC users).
