No argument from me but now, the difference isn't that much.
My point if they make the next os so much slower on the 3, how is it going to work on the weaker mini?
And I'm still waiting to hear from cynic about his claim...
ipad 3's inability to play games with full effects like the iPad 2 and 4 can.
The iPad mini is only weaker in GPU performance. The CPU is exactly the same. And for that matter, the GPU in the iPad mini and iPad 2 is more than capable of running at 1024x768. The A5X is less than adequate to drive the 2048x1536 retina display in the iPad 3. So in practice, the iPad mini and iPad 2 feel faster at some tasks than the iPad 3. It's not a deal breaker for me personally, but my iPad 3 stutters on occasions where my mini is butter smooth.
Logically, it follows that gaming performance would suffer as well. I don't know what the situation is like now, but at the launch of the iPad 3, developers had to make the decision between full resolution or full effects. Simply keeping the iPad 2 resolution wasn't going to fly, so some developers decided to run their games at about 1.6x the resolution of the iPad 2 so they could maintain the graphical effects that the iPad 2 could handle. Games that were lightweight could run at the full 2048x1536, of course.
So to overly simplify the discussion about gaming performance, we have an iPad 2 with great graphics, an iPad 4 with great graphics and retina resolution, and an iPad 3 with either great graphics or retina resolution, or some compromise of the two. The iPad 3 simply does not have the power to drive graphically intensive games at the full 2048x1536. This won't matter for most iPad 3 owners- yet. But as iOS itself becomes more resource intensive, it wouldn't surprise me to see the iPad 3 become unsupported quicker than either the iPad 2 or iPad mini.
