do you understand what a netbook is? i don't think anyone is arguing that a netbook is going to outperform a MBP, who tries to use one for those functions or for "serious use"? I think the point they were trying to make is that W7 is versatile and light enough to work on a netbook.
I can't even count the number of times people here have said "Mac's are SO overpriced! I can get a Windows netbook for $300!"
-or-
"Screw getting a Macbook, I will just get a netbook that can perform just as well"
Too many people here think netbooks are supercomputers.
