Some businesses are conservative and rightly so, momentum is slow and precise, changes are incremental and measured. Think mainframes churning through Cobol from the 60's. Bleeding edge things come and go and so do the problems they bring, but what works for years will generally keep working if left to its own devices. As for your company, there may be a business case to build a lab with XP (say most of your customers have XP). It doesn't excuse why your coworkers didn't take the initiative of figuring out why it didn't work but not everything new is awesome and not everything old is bad, you'll learn that after a few years of experience.
Furthermore you will probably soon learn that IT is there to support business not the other way around, unless you are company's goal is to produce IT products, chances are you are there to support your business unit or another company's business. You sound like you are enamored with the technology and want to play with technology for technology's sake, most veterans I've talked with are more concerned about things like uptime, scalability, change management, security, etc... Cool factor plays a part but that's a pretty poor indicator of professional skill, I've known plenty of "nerds" that love playing with new technology but couldn't design and coordinate a real IT project without all sorts of issues (thats the problem with cowboys). The best IT professionals will always keep the lights on, that's your primary goal.
