We've covered the iPad's usefulness as a digital sketchbook in some depth, but how does it stack up for the rest of the tasks you'll want to do on the move -- from client presentations to day-to-day admin tasks?

Apple's iPad will go on pre-order in the UK next week, and it's an under statement to say its highly anticipated.

The US was the first country to get its hands on the slate PC just over a month ago. In that time Apple has shifted one million of the devices.

I, myself am one of those one million that got an iPad.

I can do 90 percent of the computing tasks I need to do on the iPad.

I can use the web, check email, use Twitter and Facebook, and, most important, write.

Theoretically, I should be able to use it as my only computer for a short time.

As an experiment, I decided to see if I could use the iPad as a laptop replacement. Not forever - just while travelling.

I know the device isn't intended to replace a full-blown laptop, but that's what experimentation is all about, right?
