The graphics chipset is really old, obsolete and inadequate. Using an ISA generation card in a laptop of that age is such an example. It is impossible to understand why such an old platform was used, except for cost. Since the graphics chipset does not implement even many Windows 3.x era features, it is already slow even for such an old operating system. For instance, a lack of fast screen scrolling severely limits windows graphics updates making any 2D or 3D graphics slower than on similar videocards such as the venerable S3 Trio 64 or the Chips and Tech 6555x chipsets that were available by 1995-1996. | The graphics chipset is really old, obsolete and inadequate.

The LCD TFT screen is somewhat alright but it uses a dated technology that results in low brightness, low contrast and very low long-term performance | The LCD TFT screen is somewhat alright but it uses a dated technology that results in low brightness, low contrast and very low long-term performance. Response time is somewhat reasonable. Definitely avoid the DSTN screens as they are way too slow, ghostly, and low-contrast. | ||
The CPU implementation is quite bad. Even if the CPU is passively cooled, with no fan in the chassis, which is fantastic in terms of noise, the rest of the configuration is not that great. It seems that no L2 cache is included, a very strange design choice. This, along with the slow memory severely affects performance compared with a typical Pentium 100-133 CPU. It seems that the platform was actually designed in the first edition Pentium processors era, around 1994, explaining the quirks of its implementation, such as no USB support. Including a 100-133 MHz CPU was only an afterthought due to demand and not hinting at a good design. The keyboard is durable and with good tactile feedback. The trackpoint is mediocre in terms of reliability clearly below the level of the classic, renowned IBM quality. | The CPU implementation is quite bad.
