1983年也被称为笔记本新纪元的开始，因为从此以后笔记本的发展越来越快，便携性、功能性都有所增强，而且笔记本的输入、控制设备也得到了全面的提升，除了GaVIAln SC率先提供了触控板（位于屏幕下方），还有很多输入设备的引入值得一提。1992年诞生的IBM Think Pad 700则开始提供了指点杆。1987年LiNUs Write-Top笔记本电脑出现，这种产品率先搭载了手写输入功能。
The Newton is not the first device with a touch-screen and handwriting recognition, though. The Linus Write-Top incorporated both six years earlier in 1987, but the user has to train the Write-Top before it will recognize their handwriting.

The Write-Top is IBM PC-compatible, with standard serial, printer, external 5 1/4-inch floppy ("D:" drive) ports.
There's also a standard keyboard port so it can be used for word processing or other uses.
The optional internal modem allows transfer of data to remote systems over the telephone line.
An external floppy drive can be attached for local data storage and transfer. The internal 3.5-inch floppy is always available.
A non-volatile battery-backed removeable solid-state RAM card holds up to 512K of data, and is recognized as the "C:" drive by the
The internal rechargeable battery will supply the entire system with power for approximately 5 hours.
Although the screen is small, 5-by-8 inches, it has an attractive electroluminescent backlight.
The Write-Top cannot read any handwriting at all, until it is first 'trained' to recognize a persons particular script, which is then saved as a 'library'.
Anyone else who wishes to use the system must also train it to read their writing as well, or load a previously made library of their own.
Actually, since you teach it your specific longhand, the Write-Top can even learn and recognize Klingon and convert it into standard ASCII text. Unfortunately, the Write-Top was not a commercial success - less than 2000 were ever sold, according to sources.
Sometime before 1989, it was apparently acquired or licensed by TRW, as this
