When you need ultra-portability, great battery life but mainstream performance at the same time, one may invest >30K (sometimes >lac) for ultra-low-voltage (ULV) notebooks with Arrandale-based processors (Core i3/i5/i7-UM) even C2D SU, for example: ASUS's U and UL Series, MacBook Air /w LV C2D 1.86GHz or 2.13GHz. These CPUs are occasionally soldered directly on a motherboard to get a thinner/compact look.
Soon AMD's E-Series (Zacate) will offer direct competition to ULV Intel notebooks at prices <30K and similar or even better performance compared to ULV Intel cpus.

Really liked your previous informative posts. But this thread's title and starting post was a micro letdown

. Expecting more from ya

. Feels like you're MIA not KIA, if I get the meaning right... Lulz.
