Those of you that know me, know that I am a huge mac fan. I love my MacBook, and will tell anyone that listens that even though Mac's are more expensive upfront, you spend far less time keeping them running, as you do with Windows on PC's. Mac's just work. However, some of the software I use for work, specifically AutoCAD only works on windows. So I am also forced to run windows on my mac as a virtual machine. I won't go into all the details, but for the most part it has worked well. I do use XP, and have stayed away from Vista.
A couple of weeks ago I started having all kinds of issues with XP running extremely slow. I even did the standard Windows thing, and did the equivalent of reformatting the hard drive and reinstalling everything. That has helped somewhat, but there is still a bug in it somewhere.
However, at the same time I learned about Windows newest operating system, Windows 7. Usually I am very suspicious of anything new from Microsoft, but I took the leap and downloaded the free evaluation version of the operating system. One advantage of running thinks virtually, is that I can easily set up more than one operating system. Anyway, long story short, I am very impressed with Windows 7.0. Even though it is still in pre release form, it has worked for me without any issues, and is far faster than XP. So far, it far outshines Vista, and seems to be better than XP. One downfall for windows though, is I hear they will have several versions of the it coming out, as they have done in the past, only to add to the confusion.
Don't get confused, Mac is till the superior operating system, and the fact there is only one version of it is a big plus to boost. But if I have to run Windows too, then, at least for now, Windows 7.0 looks very promising.
