After being offline for most of the morning, the Apple Store's website is now back up and running, which means you can purchase all the new Mac hardware announced today including the MacBook Air and MacBook Pro refreshes along with the next-generation MacBook Pro with Retina display. Prices range from $999 for the base 11-inch Air all the way up to $2,199 for the base Retina MacBook Pro — a little expensive, perhaps, but considering the specs that Apple brought to the table today, it seems likely that it'll sell extraordinarily well.
