Apple is having a great year so far and its Mac computers are selling very well. Some of the Mac notebooks like the MacBook Air are due for an update. Apple is pretty good about offering an update at least once per year on their notebooks and other hardware. There have been rumors that the Air would get an update to Sandy Bridge power in July. The rumor came by way of industry sources. The updated machines are also expected to get the Thunderbolt port that other MacBooks have onboard.
