1 The 2.4GHz MacBook with 2GB of memory is available for about $1,000.  Apple's ultraportable laptop, the MacBook Air, is aimed at business travelers. The 1.6 or 1.86GHz processor is slower than a MacBook but what it loses in power it gains in portability.
A new Surface Pro with an Intel Core i5 processor, 8GB RAM, and 256GB of storage will cost you $1,300. It sounds mighty tempting when you compare it to Apple's equivalent MacBook Pro, which costs $1,500. But once you add the $130 keyboard for the Surface Pro, the total cost racks up to $1,430, which is only $70 cheaper than the equivalent MacBook Pro. And it might seem like Microsoft's most powerful Surface Pro offering, which includes a Core i7, 16GB RAM, 512GB of storage and cost $2,200, is a much better deal than Apple's equivalent MacBook Pro with similar specs, which costs $2,500.
