Should I Mac or Windows?

I really love blogging and am planning to do more in the way of blogs and websites. I will need to get a new computer soon and have some major thinking to do. I started off with a Mac. Then our whole workplace switched to Windows. Except for a couple of our designers who kept the Macs. And that is when all the trouble started. You know--the hardship when you go between the two. So now I am used to Windows. But the Macs are so neat. And if I get one but have to work with people who have the other, what am I to do? Especially since I am working on my own now and don't have a whole IT crew at my fingertips like I used to. I may try to find solutions at appletalk problems. There is some software that lets you go back and forth with ease. That is what we should have had all along. Why do computer people make these so hard?
