To me, the biggest thing that BlackBerry has over the GSII (or any Android device for that matter) is email. Nothing beats BlackBerry for email. And since that's not highly important to you, that pretty much leaves everything else pointing to the GSII, with the possible exception of battery life. However, from reports of current GSII users, the battery life appears to be pretty good. So, that may not even be an issue either.
That is arguable though. It may get emails a few seconds quicker but they are truncated and formatted like crap. I enjoy the email experience much better on android than I did on BlackBerry.
