Model would still leave out Ethernet, optical
A 15-inch MacBook Air should ship in April, according to a vendor source at CU Exposed, a UK expo which had its spring event yesterday. Electricpig describes the vendor as a "premium Mac accessory maker," and "a key player in MacBook docking solutions." Few other claims about the new Air have been made, other than it should resemble other Airs in having ports on both sides but no Ethernet jack or optical drive.
The vendor is said to be convinced enough that a new Air model is coming that it has put its manufacturers on standby, ready to make and ship new products within 90 days. The source suggests that the 15-inch system could disrupt the MacBook Pro, which has traditionally been the only MacBook to have a 15-inch option. It's speculated that Apple might at least hold on to the 17-inch Pro.
A relative handful of reports have hinted at the prospect of a 15-inch Air. The Air has proven especially successful for Apple, and the company may want to further those sales. Apple has also been shifting its design philosophy in favor of products like the Air, which emphasize thinness and simplicity over comprehensive functionality.
