Hi All, I currently have a MacBook Pro (2012) and have decided to upgrade to a 15" Surface Book 2 (probably the 512GB model). Anyone have any idea - based on their experience with the original Surface Book - what availability is likely to be in the next six months? Normally I'd wait a few weeks before pulling the trigger - just to see what early user reviews say - but if this means then waiting six months for them to become available after the first batch are sold, I'll probably just pre-order and take my chances. Any thoughts? Do people think the 15" will be hard to find between release and end of the year / January?
