The difference in weight can be important for those at the edges. I think of the iPad as an iOS device for people whose eyes aren't so good as the youngsters who make up a large part of the original iPhone and iPod touch demographic.

The heat isn't outrageous, but it is bordering on the dangerous. I know someone who burned her stomach rather badly by falling asleep with a laptop laying on her. This is now a possibility with the iPad.

For me the fragmentation comes down to whether it has a camera or not. As an owner of a original iPad, I was more and more disappointed at apps that didn't include me: many photography apps, and some games just wouldn't work. GTA3 wouldn't work without crashing before I even finished the first mission.

This will only get worse as people who are developing apps aim their performance goals at the newer devices. It's similar to when you try to put a new windows on your old machine - sure, it "works" but it is slower because you're still running on old hardware.

joining a supercomputer by just clicking a URL.. isn't that the definition of a botnet?
