I still use my iPad3 from time to time because I've yet to switch the ATT plan to the 4. After needing LTE and using the 3 for a few days. I'm not noticing any difference with that and the new iPad4. Went back and did some side by side testing. Almost no difference that I can see. Pages come in within a second or 2 in Safari. Apps seem to launch same time. I only see 2x speed if I'm rendering a movie; which I don't do that much of. I think there was no reason so spend another $900 with Apple and it needs to go back. Any one else give up on their 4 and take it back? Anyone really see speed differences in real life.
