The problem for me is that Apple seem to be moving out of the computer market, and into the electronics market. There's a subtle difference.
What the iPad seems to do within its limitations, it seems to be doing it well, but I want more from a device that claims to be so versatile. I want to be able to multitask. I want to be able to install World of Warcraft if I so choose. USB should be a given, but its not.
It's not a true computer, but its something else. Whatever it is it might be very popular, and I can even see myself wanting one in a generation or two once its carved its niche... but I'm not entirely sure I understand what it is yet.
