The DeskNote is the better performing and cheap alternative to a conventional notebook, and is upgradeable easily, but it doesn’t have the internal battery, and utilizes the regular components of the PC components (not the components of a custom laptop), helping them to keep the costs down.

Using an integrated chipset of SiS 650, which assists both the Northwood and Willamette cores, the i-Buddie4 comes along with Pentium 4 2.0 GHz processor based on Northwood core. It even has 512KB L2 cache and is designed using 0.13micron technology. The machine runs only on power from mains, and doesn’t come along with the battery, its system bus speed (or the FSB) of 400 MHz makes this i-Buddie 4, the fastest computing solution!
The i-Buddie 4 comes along with one CD-ROM drive, a 20GB HDD from IBM Travelstar, a 10/100 LAN and a 56K modem and both of them being onboard. The machine even has 4slots of USB 2.0 and a port for IEEE 1394 that is capable of the rates of transfer of up to 400Mbps. The system even uses 256MB DDR-SDRAM. Eclusive of these, you have some usual I/O interfaces such as an external VGA port, headphone jack, Mic-in, TV-out, S-video, and a parallel port. The accessories that accompany the package include a telephone cable, a video cable, an adaptor, a power cable and the installation of the ThizLinux! The i-Buddie 4 does not come preinstalled with the Windows OS.

This battery-less i-Buddie4 from the ECS is priced a lot that doesn’t make good sense really for the machine which is only a semi-mobile.
Pros

Easily upgradeable and very fast

Cons

Windows Operating system doesn’t come preinstalled, poor build quality, graphic performance is very low and is much expensive.
