Seems to me that some mysterious pc thinktank somewhere must have noticed that the netbook phenomena had peaked in terms of market share and thought we need something new to hook the "boutique" businessmen and women.
This iPad number one doesn't look like something many people would find useful but it's no coincidence that everyone else is working on something similar with proper operating systems on.
I reckon that this kind of device will be this years netbook. They'll be really cool.
Thing is a couple of my friends with netbooks have now gone back to their laptops. They thought they could put up with the limitations of a netbook for work but missed their computers. They've also got powerful desktops at home and iPhones.
So yeah. iPads, Slates, whatever will be this years boutique gadget for rich folk imho and will avoid the lid in the face problem for business meetings.
Of course eventually we'll all have power rings that project a GUI in front of us
