Apple has left the golden middle ground a long time ago and is going after the "media" types only. News flash: the margins in those youtubers-sectors are very low, hence the spending will dry sooner rather then later.
I don't think that this is a very good good laptop for media-youtuber types either. Just watch Casey Neistat's review of the new rMBP. He really wants to like it, but it's really clear from what he's saying that it's completely unsuited to his needs. In particular, the loss of the SD card slot is going to hurt anyone who uses pro camera equipment.
