Mike - I'm a little worried about your unit with all these crashes you're reporting. I got mine several weeks ago now and have not had anywhere near the crashes you've experienced.
Off the top of my head I've had about three or four isolated instances of apps crashing back to the home screen - roughly the same level of crashing as the apps on my iPhone. I don't remember Safari crashing once, and that's with heavy browsing through all my usual bookmarks, regularly, several times a day.
I'm not pulling the usual Internet kind of "well, I don't get that, so ha-haaa..." - just noting that your experience with these crashes is not usual with the iPad. What's everyone else's experience with this?
