The Store is still down but the apple.com homepage has changed.
Nothing very interesting here at all.
They upped the amount of memory in the standard configuration from 512MB to 1GB and in the low end configuration went from a 60GB HDD to a 80GB HDD.
They also removed the 1.83GHz Core 2 Duo option on the low end and now 2.0GHz and 2.16GHz are the only processor options.
You can also get a 200GB 4200RPM hard drive as an option now.
The new MacBooks will be available immediately. If anything else new comes out when the store is back I’ll let you all know.
Update: Apple Store is back up with MacBooks available
