You mean, the same OS that wastes the entire bottom right and left corners of the screen?
Just like Windows then. Except, you can't easily see what windows are open because the dock only lists what applications are open. Doh.
Only if you're stupid enough to install a virus. The same can happen on a Mac.
Not sure what you mean by this, but I can tell you that Windows does a much better job of letting its users know what their machine is doing.
I agree with the points above as long as you change the word "virus" to "trojan".
Besides, it's more of a technicality for most users anyway. Trojan....virus......just call it "bad stuff". Apple may not be prone to viruses, but they're still prone to overall "bad stuff" created by others to harm you. Saying "Macs don't get viruses" is good for marketing though.
Re: multi tasking
Open 100 5mb JPEG in windows. Try to switch between that and Office, Excel, etc. Good luck.
Luckily, I'll only open 98 5 MB images on my computers.
