I think it's mostly getting used to the fact there's an edit mode and a browse mode. To me it seems that if you create a cell, 99% of the time you want to jump into it and start typing code - not adding another cell or selecting whether it's in Markdown/Python/Raw format or whatever. I suppose my biggest gripe is that I had to search for what changed (rather than simply what's new), given how much is different from a UI perspective it would have saved me a lot of time to skim a document. It's probably awesome who want that kind of functionality, and it makes the IPython platform so much more powerful for content delivery, but I wish it had a simple "Code and execute" mode. I always wondered why people complained about extra keystrokes in applications and now I know why :P
