So that means ...
A realistically "basic" MB laptop starts at nearly $1,500.
With the shared RAM drain from the GMA graphics, not to mention the basic needs of OS X, the default 512 MB of RAM just doesn't cut it. There's little point in shelling out $1200 for a laptop with a freakin' combo drive. And for all but Granny, fairly pointless to try and scrape by on a 60 GB HD.
So $1,299 base, plus $100 for the RAM and $50 to get to a reasonable 80 GB HD, and you're at $1,449.
