It’s not going to stop working …
Apple next month will reportedly begin manufacturing the first updates to its rejuvenated MacBook Air line as the company looks to maintain the impressive sales momentum generated by the ultra-thin notebooks and limit the market opportunity for would-be competitors hoping to wedge their foot in the door.
That’s how life goes. You buy a brand new Apple device and you know by the time you buy it that it’s going to be replaced a couple of month later. That’s what’s happening now with the Airs.
Does it really matter? I don’t think so. First of all you Air is not going to stop working even though the “new” Air will have Intels new Sandy Bridge processors and maybe its new Thunderbolt I/O
Should Apple follow its current trend of using ultra-low-variants for the 11.6-inch MacBook Air and low-voltage ones for the 13.3-inch models, consumers can expect to see new 11.6-inch MacBook Airs sporting 1.4GHz to 1.6GHz Core i5 and Core i7 chips and 13.3-inch MacBook Airs with 2.10 and 2.30GHz Core i7 processors.
And as the latest Air is as snappy as it is, I am not seeing any issue in terms of speed. And as your “old” Air is using the Penryn Core 2 Duo in a low consumption version it might be still better in terms of battery life.
