u are totally wrong. u are not paying for the pro tag.
the build for Macbook and Macbook Pro is different! One is cheap plastic one is solid aluminum. And Macbook ram up to 4G while Macbook Pro up to 8G.
btw, Acer to me sucks, battery dies out fast and the tech support is non existent.
If you take care of ur notebook well I don't see how build quality is important. And if I wanted something powerful I would use my desktop, not a laptop. 4GB RAM is enough for me.
I agree tech support for Acer sucks, my laptop was ready for collection after servicing and they didn't even say anything, they say must go check the website yourself. But battery I think depends on which model you get and how you use it, as I said my laptop can last a full 8 hours if doing Word document only (with occasional browsing of the net)
