The Libretto 1000SS went back to using the smaller screen, and is slimmer than previous models. There are some new models available called the Toshiba Libretto ff1050 and ff1100. Click here for more details on these. The Libretto is only slightly large than a VHS videocassette. All Librettos have a high-quality colour display, using TFT technology to give a very clear and bright image.
Some people find the keyboard too small and fiddly to use comfortably, others love it.
On Librettos up to the 70, there is no sound input facility. There is on the Libretto 100 and on subsequent models. See the Toshiba Libretto specifications page. For the Libretto 100, there is a 32Mb upgrade available, giving it 64Mb in total. It, uh, charges the battery.
