I am trying to gather info on Windows UltraPortables that can be considered competitors to the MacBook Air. Two candidates are the Alienware M11x and Toshiba Portege R700-ST1303. Configured similarly to the best 13" MBA, they price out very close. I am trying to keep an open mind, but there does not appear to be anything in the PC world quite like the MBA. Can any of you dispute that? Are there other candidates?
