In the beginning of the new Millenium, Toshiba launch Libretto L series, which only available in Japan, to compete with Fujitsu's P series (FMV-Biblo Loox) and Sony's VAIO which run on "small note" platform, a breed of notebook with the debut Transmeta's Crusoe CPU. But it seems that Toshiba has advantage because it has already launch many of "small note" platform Libretto lines for quite sometimes since the very first Libretto, Libretto 50 with Intel's Pentium 166-MMX mobile version (check Toshiba site for history). Here I got some models of Libretto L series comparing side-by-side, I made this because I was confused about their differences (of which I marked by bold characters).
