The issue is simple.. Comparing yourself directly in a world where things can change in a day is dangerous, because if the competition changes its abilities tomorrow, you could look like a fool, rather than simply showcasing your own abilities. Also, unless you have the general brand loyalty that apple does, you do risk alienating some people who may have come over to you by saying they are fools for what they are using now, rather than simply saying, that's a good product but we can do it even better, come check it out. Its all in delivery.
As for apple seemingly stuck in their own mud, I have to wonder if we aren't seeing them taking a more measured approach, with small updates in between big ones, and that maybe sometime in the next year we will see some big changes, and then set quite for a couple years, and then be hit again. Might be better to do that than try and recreate the wheel every year, as some seem to be trying to do. It also could be that are trying to get what they really want done right before they release it, and have had some troubles making that happen. Hence the size of the current ipads still being way to heavy IMHO. There current yearly updates have been small and incremental, but sometimes I wonder what more they could do to their existing product lines that would be large and happen every year.
