Most (not all!) Apple laptop buyers are just surfing the internet and doing light “Office” work like word processing and Quick Books. They can do that with a 50% cheaper Windows7 laptop
Apple has two big money makers. iPhone and laptops especially its high end laptops. But the average Joe who needs a solid 15.4 in laptop for $400 or less? There are plenty out there made by solid companies such as Toshiba, Dell, HP, Acer etc. I see those deals every week. My advice to such buyers is to only buy one with Vista Home Premium so they can get the free Windows7 upgrade
And if the consumer has $400-$600 to spend he can do even better. And any laptop with Vista Home Premium gets a free upgrade to Windows7
Windows7 runs great on 2Gb memory. This is exactly what my laptop has and a weak dual core processor
Which will probably endure less than half the time the Macbook will.
