All true, but I am going to be that nerd and point out that there were indeed commercial devices with lithium ion battery packs in them in the mid to late '90s, especially so in the late '90s. By 2000-2001 you couldn’t escape the damn things in cameras, disc players, PDAs, etc. So yes, it did take relatively forever for the technology to become commercially ubiquitous, but not that long. (And yes, the first couple of waves of Li-Ion batteries were indeed crap, and had all of us geeks clamoring for gadgets that still took AA’s for a while.)
