This photo shows the Asus Eee PC 900 next to HP’s 2133 Mini-Note PC, two miniature laptops that are approximately the same size and both of which cost less than £500.

As should be apparent from the picture, HP’s model is slightly wider, which enables it to have larger keys and thus makes for easier typing. The Mini-Note is also more polished, with a brushed aluminium case, while the Asus feels rather plasticky by comparison.

However, the Asus has the advantage of weighing under a kilogram, while the Windows version of HP’s pint-sized portable weighs almost half again as much at 1.46kg.

There are other notable differences; the Eee PC has Windows XP installed (although the Home edition rather than Professional), and with 1GB memory, it feels as responsive as any other Windows XP system. The HP Mini-Note ships with Vista Business Edition, and despite its having 2GB of memory, Vista is a severe drag on its performance.

Asus also ships the Eee PC with 12GB of Flash solid state disk (SSD), while the HP model has a more conventional 120GB hard drive. Both have an 8.9in screen, but the Eee PC has a native resolution of 1024 x 600, while HP’s is a step up at 1280 x 768.

In early tests, the HP Mini-Note appeared to have a longer lasting battery than the Eee PC, but a full report will appear in a future issue of IT Week.
