Re: Laptop speed
Unless you massively benchmark, and time your saves, your work, etc. you won't really notice that big of a difference. Especially if you don't game. Try getting a faster harddrive if possible; megahertz won't be your achilles heel here. The duo is such a nice cpu that any level of operating will be superb. Save your money.
Macbook Pro and Logitech z5500s. All you really need.
