I have done some research and am leaning toward the $1,600 Macbook-Based on the reviews I have seen, it seems to offer the best performance for the price. It is not FAR BEHIND the entry level MBP (except of course on the Quake 3 benchmark) -but a lot less money. I figure with either machine I would get 4GB-Apple actually seems to charge a reasonable price for this. Does anyone have an opinion on the current "sweet spot" for Mac Laptops? Probably going to buy today, so any input is appreciated. Thanks!
