Reviews for the Dell Inspiron 1420n
Source: Ars Technica

The Dell Inspiron Notebook 1420n with Ubuntu preinstalled delivers software freedom and solid value. For serious Linux enthusiasts who are already comfortable handling the various idiosyncrasies of the platform, Dell's preloaded Ubuntu laptop is a practical and cost-effective choice that eliminates the need to perform a manual installation and provides Linux users with a means of dodging the odious Windows tax.
Although I consider this product a strong buy for experienced Linux users, I don't recommend it (yet) for users who aren't already familiar with the operating system. Ubuntu's prodigious ease of use is diminished by a litany of frustrating minor hardware support problems that many average computer users will not be inclined to resolve. The lack of display hotplugging functionality in Ubuntu 7.04 makes this system a nonstarter for some business users who depend on secondary display support.

Intel Graphics Media Accelerator (GMA) X3100: Intel Graphics Media Accelerator (GMA) X3100 is an integrated (onboard) graphic chip on a Mobile Intel 965GM chipset. It is the successor of GMA 950 and features a fully programmable pipeline (supports Aero Glass fully and DirectX 10 with newest drivers). The peformance of the X3100 is clearly better than the GMA 950, still demanding modern games won't run fluently.
These graphics cards are not suited for Windows 3D games. Office and Internet surfing however is possible.

Intel Core 2 Duo: This is the Core Duo and Core Solo successor with a longer pipeline and 5-20% more speed without more power consumption. As an addition to the Core Duo design there exists a fourth decoder, an amplified SSE-unit and an additional arithmetical logical unit (ALU).
The Core 2 Duo for laptops is identical to the desktop Core 2 Duo processors but the notebook-processors work with lower voltages (0.95 to 1188 Volt) and a lower Frontside bus clock (1066 vs 667 MHz). The performance of equally clocked notebooks is 20-25% lower than Desktop PCs because of the lower Frontside bus clock and the slower hard disks.
