N900 software + bigger box = fully expandable iPad

My son has an iPhone - simply because he could not wait. Now he has seen my N900 he is looking to when the iPhone contact runs out .... In the office, my N900 is just a window on the desktop machine and I use a proper keyboard. All we need is a bigger screen version of the N900 - if we ACTUALLY need anything at all?

I might be biased - I haven't used windows on the desktop for a couple of years so using a hand held that works exactly the same ......
