好圖!但有個疑問,點解Wireless transfer speed係2000至2002年間突然跌咗咁多?仲要係跌凸到差過1996年?Bittermelon
原來一間 Metricom 公司 2001 年破產，它是最早提供無線上網的公司之一。另外，翻查圖片來源才發覺，圖中的 wireless 只計美國流動電話。
We won't expect too much of improvement in Battery capacity unless there is a fundamental breakthrough. As one of the insider of the trade has put it, a high density battery is in fact a bomb packed with too much energy waiting to explode.
