I was looking at Wegener Medias site...iBook

And I looked at the iBooks.. My Birthday is in 2 weeks so I though, hey, birthday present..

My questions...

All apply to 12" only

1. 500Mhz/10Gig or 600Mhz/15Gig... Worth the $50? I'm also getting the 256mb Ram upgrade.

2. Battery life. Has anyone ever bought an iBook from them , aand how was the battery life?

Thanks!
