iPad 2 will be out in about a week.  Also, Apple introduced a new magnetic "Smart Cover" to replace the first-generation case.  They say the iPad automatically sleeps and wakes when you close and open the cover, but who can be sure?  This seems to me like trusting the refrigerator manufacturers who promise that the light goes out when you close the door.  Whether Apple has earned that kind of trust or not remains to be seen.
