Sheesh.
Maybe some people buy a new tablet every time one comes out, but I just don't see that as the goal here. So the new iPad has better resolution *and* a killer CPU/GPU. That's great. If I didn't already have a tablet, I would find this excellent news.
But I do own a tablet, and it is suitable for now, so I'll keep using it. When it is no longer serviceable, or the apps I use demand more than it is capable of, I will upgrade to whatever's newest then.
I will not, however, whine and moan about how this doesn't put the iPad 2 to shame, and how Apple must be a glutton of a company to expect me to throw away my existing device in trade for this. I just don't think that's the point. The fact that I have a tablet is no reason for Apple to stop making their flagship model incrementally better.
If this new product doesn't apply to you, fine, move on. For someone else, it's timely and a good reason to jump in. Relax, OK?
