The idea of notebooks without batteries has been knocking around for a while now, and although at first its seems like a strange concept, the number of people choosing to use portable PCs as desktop replacements means it is becoming a more realistic option. Or at least that's what notebook market newcomer ECS hopes.

At the Computex show in Taipei ECS is showing the Desknote which looks like a notebook (or more accurately like an iBook), but it uses desktop components (Desknote geddit?). The benefit is that you get a powerful, low-cost specification in a portable chassis.

But that's not the only difference between the Desknote and a regular notebook – it also has no battery. This undermines its status as a portable product, but won't make much difference if you only want to use it a home or work while tethered to the mains.

Ditching the battery also means ECS doesn't have to worry about battery life, so it can put in powerful desktop components that would otherwise suck the power from the battery. If you must use it on the move, though, you can buy an external battery for the Desknote — but that would rather defeat the purpose.

ECS isn't some lone voice crying in the Computex wilderness, either, as notebook manufacturer Mitac was also displaying the MiNote 8500 another notebook with no internal power supply.

Better known for its motherboards, ECS' entry to the notebook market is due to a recent merger with OEM (original equipment manufacturer) notebook maker Alpha-Top.

Alpha-Top used to make notebooks for Apple, but we're told that the Desknote's uncanny resemblance to the iBook is purely coincidental. As coincidental, no doubt, as the decision to sell the Desknote under the iBuddie brand in the Asian market.
