The entire time getting my bachelors degree I used a mac laptop. It seemed like every teacher I had was only interested in the Microsoft tools. It made it a lot harder to for those classes using .NET using virtual PC or constantly looking for an equivalent tool to use instead of the windows tool that the teacher knew about. I didn't want to go through that again so in an effort to think ahead I bought a windows laptop. The thing is here is that all the teachers seem to be acting much closer to the computer science thinking. They concentrate on the problem instead of just teaching the tools. They make sure that all the tools are usable on any platform. I think that this is also because the majority of the teachers here use mac laptops for their computers. (It is the exact opposite of my old school- there, there was only one of the computer science teachers with a mac laptop, here there is one with a windows laptop.) This means that I am still in the minority. Only now I am stuck with a laptop that I have to devote time to updates, anti-spyware, and anti-viruses every week. I have installed Linux on a partition but don't have time to configure it correctly so only about half the stuff is working... ugh, I just can't win.
oh well this laptop was just a temporary until Apple releases an Intel Powerbook that I can dual boot into Mac OS or Windows.
