I very rarely run into issues with the lack of flash. But it really depends on what sites you visit. Remember this is not a replacement for your computer. It is a device that you will use to do some of the things you did on your computer, some of the things you did on your phone and some of the things you did on other devices. It is a mix of all of them. It totally changed my home use as I used to always have my work laptop booted up while at home to do my internet browsing. This in turn led to me doing some work in my off time since the computer was on anyway. Now, I rarely boot up the work laptop at all and do all my browsing while at home on the iPad. For me, it was a HUGE change.
