standard係37W
所以28W已經係low voltage

我覺得以現今Apple既market 同產量，絕對唔可能叫多。
每種產品都係兩種呎吋，簡直係精簡到不行！
主要係某d舊型號要等fade out

科技同電腦運算能力爆炸性增長，令產品性能提升
例如，mba 已可勝任video editing 工作，iPod touch 5 已有不錯的用家體驗
令產品分野縮小
蘋果應留意，除了避免產品線重叠，還應突出產品獨特性

If you study Intel's SKU carefully, the suffix U refer to Haswell-ULT
Unlike the conventional ULV it is a new line using BGA socket and SiP packaging, and therefore lower TDP than the Haswell-MB
When you compare 4258U/ 4278U to the 42XXM, 43xxM chips, they are not even a side grade, but an upgrade from HD4600 to Iris 5100 graphic, and more expensive as well

The ULV processors, now both present in ULT and ULX families, are running below 2GHz with 15W or lower TDP
