Price: $1049 - $1049
I'm a switcher. Used PCs all my life, but when Apple released the Macbook, I reconsidered. It would have been easier to stick with PCs, but where else could I get a laptop that was less than 1" thick, with a core duo processor and so many slick features for under $1200? Vaio's are cool but too pricey.
Bottom line with the Macbook is that it takes away any reason you might have to stick with PCs. Still not convinced? Get bootcamp and use the Macbook with Windows.
On the downside there are some build issues (I've heard many reports of buttons sticking, etc.), and it tends to run pretty hot. So, it may be worth it to wait a couple months until Apple can work out the kinks of this new product.
