TweakTown posted a review on the Lenovo ThinkPad X300 Series Notebook

The X300 notebook has an Intel Core Duo SL7100 (1.2GHz, 4MB L2, 800MHz FSB) CPU. The monitor is a 13.3” WXGA+ TFT (LED backlight). There is a 3x3 UltraConnect II which is a connectivity suite offering wireless LAN, UWB (UltraWide Band), Bluetooth and numerous wireless WAN choices including a system that utilizes native GPS functionality that is built into the X300.

The hard drive is unique in that it is a solid state drive (SSD) 64GB in size. What this means is that the hard drive is not a rotating disk in the traditional sense, but rather comprises of several chips with addressable memory arrayed in a specific format to prolong the usability of the SSD drive.
