4.3 works fine here except at times after watching a you tube video started from a web page , when returning to the web page it turns white and safari crashes?
I just did that with no issues.
Maybe an isolated case?
Try this...
Watch about half the video in the link below,then hit done,
And double click to open safari...
When safari opens I just have a white page and I have to shut it down and restart?

My iPad1 is noticeably faster with 4.3. I have no idea how or why some of the previous posters report the opposite performance. Because of this improvement, it's made me even more steadfast and confident in not upgrading to iPad2.
For me, with 4.3, my 32gb WiFi seems snappier, but my 32gb 3G seems like it has a slight lag when opening apps and reacting to operations.
For those in this thread that are faster, is yours a WiFi? And for those who say it's slower, is yours 3G?
