What seems obvious to me is that the iPad, like the iPod Touch, is designed for a different range of uses than a laptop/desktop computer system. Buy the device with the right functionality for the uses you have in mind.
HI Godfrey - Uwe
While I agree to some extent (completely about the intent and philosophy), I would have thought that Uwe could find a way of updating his website on the fly - one possibility would be a logmein connection to his base computer (the logmein app on the ipad is pretty fab).
Which brings me to another point, which is that whereas logmein / RDP / VNC and Citrix connections were all perfectly possible with the iphone / touch, actually doing anything was rather a chore (i.e. read impossible). However, the iPAD is quite a different kettle of fish - I can see that it will be very powerful for connection to client sites at a time when it might not be convenient to have a laptop around.
In addition, a quick hunt for html on the iTunes store finds quite a few html editor applications for the ipad:
Web Page Developer looks pretty good (even previews page).
eWebEditor also looks quite good (but I haven't looked properly).
Any way you can look for yourself
