Silicon Rumors is reporting that the next MacBook Airs will finally have 3G cards built in. This follows evidence from Apple's Job postings looking for laptop 3G QA engineers which were quickly pulled after being exposed. Silicon Rumors also thinks that the new MacBook Airs will drop significantly in price which might quiet those looking for an Apple Netbook.
They are thinking between $1300 and $1500 for an entry level MacBook Air with SSD and maaaaaybe GPS.
