After reading the experiences of many of you that have upgraded to 4.2.1, I am holding off on upgrading. I understand the value of folders, but some of you are having various problems and issues with everything else. This is really distressing. And I do not like the fact that the rotation button has been disabled. That is absolutely ridiculous.
This upgrade needs to SUPPORT the millions of first generation iPads and their owners, not confound and frustrate them.
I'm staying with 3.2.2 for now. I can live without multitasking and folders for the time being until we see something better than 4.2.1. And giving us a FREE upgrade does not make it any better. I paid good money for the 64 GB WIFI + 3G. I don't need any surprises.
