I know, everyone always posts about some laptop that they think is a contender for the title of portable machines etc... I think I have found a windows based machine that fits into the category for MBA contender as far as light, small and portable goes. http://www.asus.com/Notebooks/Superior_Mobility/ASUS_ZENBOOK_UX21E/ Just picked up the i5 version for a work PC, is so far a fast, powerful and comfortable to use machine. Is also very pretty! Is not quite the same as the MBA, but s very close in design and function.
