The laptop's case has reasonable plastic quality, although the display's unit construction is prone to cracks due to the poor hinges and a lack of continuous metal frame around the LCD screen. Access to the hard-drive is straightforward, requiring only a single unscrew to pull out the hard-drive tray. Access to the RAM, cooling, CPU is quite simple as only two top screws and a cover to be taken out that secure the keyboard. The cooling system is quite adequate for the designed CPU and can be easily upgraded on the 900B model, suggesting good durability.

A nearly , quite slim, business laptop, released in 1999. It had a good mix of parts and a slim chassis. The choice of PC-100 SDRAM and dual RAM sockets, as well as graphics chipset, make for a good all-around laptop. By 1999 the laptop was already obsolete due to the video chipset choice but this was standard for IBM laptops of its time, with no 3D hardware rendering support, no matter how rudimentary. The system runs reasonably well Windows 2000 or Windows XP, if you really need it, but Windows 98 SE is the best choice.

 

The graphics chipset is below average for such a great CPU. The great scaling support make it possible to have very sharp output on the internal or external display, although less smoothly than on modern computers. It depends on taste if you like or hate this scaling mode without any blur but some small rough edges. Overall, the Neomagic graphics chipsets were very fast for 2D operations, definitely faster than Trident or Cirrus Logic Chipsets and Chips andTech 6555x chipsets in just about every respect. The Neomagic graphics is the top performer on 2D graphics both for compatibility as far back as Windows 3.1 and DOS as well as competitive with Chips&Technology or S3 Trio 64 videocards. No real improvements due to the additional video RAM available on the 600X.

The LCD TFT screen is somewhat alright but it uses a dated technology that results in low brightness, relatively low contrast due to the vertical rather than horizontal, higher power CCFL sidelight.

The typical CPU implementation is very good. The Pentium 3 CPUs are Coppermines so they release heat slightly less than the previous model's Pentium II CPUs on typical workloads. The active cooling is quite good, not overly noisy, reliable, relatively easy to clean. The inclusion of an USB 1.1 port is a major feature. The keyboard is durable and with good tactile feedback. The trackpoint is very good, being quite smooth, predictable as well as with quick response at the classic, renowned IBM quality. The palm rest is also very comfortable.

The removable drive tray is a nice feature, offering both DVD-ROM/CD-ROM and Floopy drive support. The rechargeable battery can be easily removed or replaced. The BIOS and timekeeping battery is a standard CR2032 3V button cell.

The chassis was slim, light, comfortable due to rounded corners. The laptop's case is quite durable except for the rubberized coating. This is the single most annoying feature of the laptop, as the smell, dirt and stickiness of its gets worse as the laptop aged. Unfortunately the rest of the chassis also has problems due to the slight brittle plastic that frequently cracks due to age or shocks, especially for the frame around the kwyboard and screen. The lid closing latch is well designed and durable. The display hinges are very well engineered even if they may not look to be anything special. The integrated speakers are quite good for a laptop with no special audio quality features.

Software support is great for reasonably modern (for its time) operating systems. Due to the video chipset Windows 98 is the best choice of operating system. Good DOS sound support is present due to the Crystal Audio chipset that is Sound Blaster compatible but it is somewhat less refined for older MIDI and software support in MS-DOS, as it is slightly difficult to configure out of the box.
